Roo-B

A frightened little Roo-bot that slipped out of Gelimer's lab during Xenon's escape.

Equip this Roo-bot to obtain the skill, which will grow in power as you equip more Roo-bot pets (max 3). This Roo-bot will become bigger as you fight enemies around your level. Eventually, it will reach Giant status and cast a particularly awesome buff on your every 5 minutes.
