The girls have to do a project for school with Bubbles doing a biome for hers. When she can't get it right, she ask Blossom for help who agrees. But Blossom finds herself likewise doing favors for other people of Townsville, which puts off her promise to Bubbles. Buttercup tries to fill in, but naturally her "expertise" ends up causing more trouble.
Tropes:
- Cat Up a Tree: One of Blossom's tasks. Interestingly, the cat is Mojo's.
- Cry Laughing: Bubbles seems to like the biome Buttercup helps her make, but pretty soon she breaks down crying at how horrible it turned out.
- Egging: Buttercup's project is about dropping eggs. She doesn't realize that she's supposed to find a way to drop the egg without breaking it; she just likes smashing eggs.
- Fluffy Tamer: Blossom manages to tame the biome monster so that the school kids can climb on its back.
- Go-Karting with Bowser: Blossom saves Mojo Jojo's cat from a tree, the two of them acting very civil to each other for the time being.
- Make My Monster Grow: Due to using marshmellow goo on the biome, its chemical reaction to it cause it to morph into a giant monster. Luckily they mange to tame it.
- Never My Fault: Buttercup takes no responsibility for her action in creating the monster, blaming Blossom for letting it happen. Ironically when Bubbles gets an A on the project, she tries to take partial credit.
- What the Hell, Hero?: Buttercup gives one to Blossom for neglecting Bubbles. Bubbles likewise calls her out on it as well.
