Olive is currently living in Stacy's second closet, where Stacy can be open to unlimited mushroom stew to eat.
Stacy found Olive and gave her a place to live in the room originally titled "Dogear's second Closet of Cloaking". The room has since been given a red/white chequered carpet to match Olive.
Stacy at the time didn't know all Mooshroom's were female, so she named her 'Oliver'. The following episode, Stacy mentioned the Mooshroom being female so re-named her 'Olive'.
Olive has been Stacy's primary source of food throughout the series, with the recurring disadvantage being the fact that mushroom stews don't stack in the inventory.
- 'Oliver' and the stew was meant to be a reference to 'Oliver Twist'.
