Chocolatey goop is obtained when a Chimp ice melts. To avoid getting a Chocolatey goop, players must cast ice spells from the ancient spellbook on the Chimp ice. The Chimp ice has to be dropped, then the spell must be cast on the ice. The ice will automatically be retrieved in the inventory.
It is similar to items like Flail dust in that it has absolutely no use, and as such is recommended to simply be destroyed in the unfortunate case that a player obtains one.
Beware: Ice Rush cannot be used.
