When hurt they roll into armored defensive balls, but they're small enough for Mongo to pick up and crunch whole — 'like blood-filled hard candies.' It's mid-skirmish with the Zlurpies that Mongo hits level 15, reaching his full pony-sized adult form.
Waist-high, semi-intelligent armadillo-like warriors that curl into hard armored balls when taking damage.
