"It's a Wonderful Leaf" (originally titled "A Bushroot Christmas") is the Christmas episode of Darkwing Duck. The episode's title is a reference to the classic Christmas film It's a Wonderful Life.
The episode opens on Christmas Eve at the St. Canard shopping mall, where Bushroot, observing the hostile behavior of the other shoppers, finds himself regretting his decision to have waited until the last minute to do his Christmas shopping. While avoiding the frenzied shoppers, Bushroot ducks into a garden shop and starts looking to find presents for the flowers he's able to communicate with. But just as he's found a watering can that would make a perfect gift for one of his plant "friends", another customer takes it from him and knocks him into a nearby barrel. Then, when he accidentally scares a little girl, the girl's mother attacks him with a rake. Bushroot runs out of the store, only to get chased out of the mall by an angry mob. Furious with the horrible treatment he just received from the not-so-jolly mallgoers, Bushroot vows to ruin Christmas for everyone else in St. Canard.
Meanwhile, at Drake Mallard's house, he and Launchpad are decorating the Christmas tree. Just as they've finished, Gosalyn comes riding an old sled downstairs and around the living room until she crashes into the tree. Gosalyn apologizes for wrecking the tree, and Drake takes his old sled from her, only for it to disintegrate immediately afterward. Gosalyn wants to open her presents right now, but Drake insists that she wait until tomorrow morning. Gosalyn of course attempts to unwrap her presents early anyway, but her attempts fail due to Drake having put an alarm on top of the (now-fixed-and-redecorated) tree.
Meanwhile, Bushroot goes to a nearby Christmas tree lot that strangely still has a lot of trees in stock despite it being Christmas Eve, and orders all the trees in the lot to "rise up against their oppressors" and join him in his plan. First, they return to the mall, where Bushroot has one of the trees enact revenge against the customers who attacked him in the garden shop earlier. Specifically, he has the tree steal a doll from the little girl and make it look like the guy who took the watering can stole the doll. Then, after having another tree make it look like another customer stole the bell from the mall's Salvation Army Santa, Bushroot's next step is to kidnap the mall's Santa and pose as the big guy himself. As a "Sinister Santa", he displays all sorts of Grinchiness towards the children (and gets a visit from Herb Muddlefoot) until the little girl's mother returns and gets the kids' parents to chase him out.
At that very moment, Drake and Launchpad happen to be doing some last-minute shopping themselves when they suddenly hear customers complaining about their things being stolen. Drake goes to change into Darkwing Duck, but accidentally puts on a Santa Claus costume instead, so he decides to go undercover as a mall Santa to search for clues. Unfortunately, the mallgoers mistake Darkwing for the Sinister Santa and chase after him, but he manages to avoid their wrath by hiding behind a tree and switching to his Darkwing outfit. Darkwing suspects that "some sinister force is sapping the season's spirit", at which point Bushroom reveals himself ("I'm not really sinister; just misunderstood"). When Darkwing lashes out at Bushroot for what he's doing, Bushroot simply responds "Everybody's got to celebrate in their own special way," and then sics three of his trees on Darkwing and Launchpad before escaping. Darkwing shoots one of the trees with his gas gun, covering it in decorations (much to his surprise), and then he and Launchpad escape while the trees are distracted by this. After avoiding the trees' pursuit, they begin following a trail of pine needles that Bushroot's other tree minions left behind.
Bushroot, in the meantime, has stolen a flatbed truck and is driving around the neighborhood, ordering all the trees in the houses (which are apparently receiving his orders via the stars on top of them) to sprout arms and steal the presents spread around them. However, when he comes upon the Mallard household, he finds it doesn't have a star on top and puts it on before ordering it to steal the presents. When it does, though, it sets off the tree alarm, much to Bushroot's dismay. Gosalyn and Honker see the tree running off with Gosalyn's presents and, despite the tree subduing them by throwing a wreath around them, they chase after it.
With the stolen goods, the trees gather onto Bushroot's truck and he starts driving off, thinking his plan is a success. Suddenly, Darkwing and Launchpad catch up to him on the Ratcatcher. The Duck Knight jumps in front of the truck and lands on the windshield, only for Bushroot to stop the truck and then run over him. Gosalyn and Honker catch up to Darkwing at this point, and they all get into the Ratcatcher to resume pursuing the plant-based supervillain. In the process, Darkwing and Launchpad get knocked off of the Ratcatcher and land on a plastic Santa-and-his-reindeer display. Gosalyn turns the motorcycle around and lassos the plastic display, dragging it along until it goes flying into the air with Darkwing and Launchpad hanging on to it.
Bushroot pulls up at the front of the Christmas tree lot, thinking he's lost sight of his pursuers, when he suddenly sees Darkwing and Launchpad coming in for a landing on the plastic display. Bushroot and his trees make a run for it, leaving behind most of the stolen presents, just as Darkwing and Launchpad make a crash landing. Just as they emerge from the wreckage, Gosalyn and Honker then crash the Ratcatcher into them. Gosalyn wants to keep all the presents that Bushroot's minions left behind, but Darkwing tells her, Launchpad, and Honker to return the presents to their rightful owners while he looks for Bushroot.
It doesn't take long for Darkwing to find the half-plant mutant, as Bushroot captures him with a lasso of Christmas lights. When the Duck Knight threatens him with his gas gun, Bushroot warns him that he might upset his new best friend - Douglas Fir, a giant Douglas fir tree. The tree knocks Darkwing into a giant candy cane and then throws a star at him ninja-style, but Darkwing hides behind a fire hydrant to avoid the star. Bushroot orders the rest of his trees to throw everything they've got at Darkwing. In the process, Darkwing ends up pulling the fire hydrant out of the ground, causing water to shoot out from underneath. Darkwing grabs a shovel from a nearby snowman and uses it to direct the water at the trees and Bushroot, freezing them.
After leaving the frozen Bushroot for the police to arrest, Darkwing catches up with his group. Launchpad informs him that they managed to return all the gifts, but they were unable to find the Muddlefoots' presents. Honker glumly heads home, but luckily, Gosalyn has an idea to cheer up her friend. Shortly later, Darkwing, dressed up as Santa, shows up in the Muddlefoots' house (during which he causes Tank's attempt to trap Santa to backfire on him) and gives them Gosalyn's presents. After that, while heading back home, Darkwing tells Gosalyn that he's proud of her for giving her presents to Honker's family. Just then, Launchpad finds a sled on the doorstep, with a card addressed to Gosalyn from Santa. As Gosalyn goes to play with her new sled, Darkwing wonders who gave her that sled and then, looking in the sky, sees Santa and his reindeer flying overhead.
"Well, another fiendish plan nipped in the bud."
