The Keypers characters depict animals (including a snail, ladybug and turtle) and have small compartments which are intended for children to hide things in. The large adult Keypers have special keys so you can lock and unlock the compartments they have located on them. The small baby Keypers have a slit in their backs so you can squeeze, open and then hide things inside. The Keypers also have small Finders for friends. The Finders help the Keypers find lost items.
