Young Teroamps are left to fend for themselves at a very young age. What the creature lacks in strength it makes up for in nimbleness, enabled by its electric prehensile tongue. Over time, the Teroamp grows into Tarrawatt, temporarily losing its electrical abilities.
The Tarrawatt is a solitary creature until it reaches adolescence and is subsequently accepted into a tribe. Its physical appearance gradually changes to mimic the features of its pack. This is also when it becomes a biped. Its dormant electric powers are jumpstarted by ambient electricity emitted by its companions.
