Tatou

A monster with sharp spikes growing from its back. It charges in to attack at great speeds the moment it sees humans. It retracts its arms and legs into its hard shell when going to sleep, so forcing it to wake up is not that easy to do. Beware, though, as the tatou sometimes fakes its sleep so that it can strike unwary preys, so it is advised not to let your guard down, even if it is in its shell.
