Deposit the indicated number of Rapo coins in the town fountain (wishing well) to unlock the corresponding bonus:
Note: After unlocking the Developer's Grove town, tap the fountain (wishing well) with the stylus to switch between the normal and secret town. The secret town is a small area where the NPCs are the game's developers.
Tap the stylus inside the mushroom patch behind the astronomy lab to find a hidden message. Note: This only happens at certain times.

This trick only works if there is a template from the Book Of Life directly next to a Shadow Walker. Try not to touch the template before you kill the Shadow Walker. Jump on the Shadow Walker three times. While you are in the air from the third jump, go toward the template. Take it, and the Shadow Walker will die twice.
