Firstly, Lion's strength is needed to topple the tree, revealing a hole where RTBToL: can crawl in. Secondly, RTBToL: will lower RTBToL:'s head, making it easy for RTBToL: to shoot its eyes with the RTBToL:. After that, RTBToL: throws a grenade-like fruit to the group, and when the grenade is about to explode, RTBToL: is required to kick it back to the creature. Once all the remaining eyes are damaged, RTBToL: will explode, leaving the apples behind for RTBToL: and friends to use them.

Nomenclature
