|Season 1, Episode 26|
|Air date||Febuary 15,2013|
Banana Quest is the 26th episode and the series finale of Planet Sheen.
When Nesmith catches a cold, Sheen figures the only way to fix him is by feeding him a banana, so he goes with Doppy and Aseefa to find one. However, Dorkus is in high pursuit of this fruit as well (believing it is some sort of treasure) and will waste no time making sure our heroes don't reach it. Can Sheen find the banana before Dorkus does?
- Although this is the series finale, Sheen does not return to Earth. It is unknown if he'll ever go home. However, in the Jimmy Neutron episode, "The Tommorrow Boys", it implies that he DID return to Earth. However, the futures were just predictions, so it doesn't mean it will happen. There's also speculation that Planet Sheen may be non-canon, but this isn't confirmed, as of the present time.
- There was going to be a TV movie about Jimmy and the gang going to save Sheen, but it was cancelled due to low ratings.
- Another reason the show was cancelled early was due to production costs and the writers moving on.
