Episode Title:
Yoko's Secret.
Episode Description:
When several Galaxy High teams are taken on a class field trip to an exotic planet, they are warned to only observe the environment and not to touch anything. Not heeding her teacher’s warning, Yoko spots a cute, tiny little alien creature and covertly confiscates it to take back to GH as her pet. Back at Galaxy High, Yoko goes to extreme lengths to keep the pet a secret from the faculty and other students. But one night, after giving the cute creature a bath, it begins to multiply like mad, budding into hundreds of nasty identical aliens.
