Aseefa is a Glimmorian -- a blue yodeler with a ponytail that works as a third arm. She is also a tomboy, a beast-master, a great warrior AND the object of Sheen's first raging space crush. How could any Earthling resist?! She's so quirky, cute and punky! But Sheen will have to resist for now, because he can't tell if Aseefa likes him back and he's too nervous to ask. She's so tough! You wouldn't wanna mess with her either!
Sheen crash lands Jimmy Neutron's 'borrowed' rocket on Zeenu, has tons of misguided adventures and deals with the planet's weird creatures and a stranded NASA-trained, talking chimp who joins Sheen on the quest to get home.
