The Jellybean Pouch is an upgradable storage for the Jellybeans that a Toon holds. The maximum hold for the pouch is 250.
If a Toon receives an amount of Jellybeans that can't all be held inside the pouch, the pouch will "cap" and the extra beans will go to the Jellybean Bank.
Every new Toon is able to carry up to forty (40) jellybeans at a time. There are multiple Toontasks that allow a Toon to upgrade their hold from 40 to 60, 80, 100, 150, 200, and then finally to 250.
