Thinpers are new types of Beetleworx and were constructed by Gremlin Prescott.

Thinpers are stronger than regular tankers. Thinpers are capable of throwing balls of thinner and electricity bolts. If you get too close, they can pick you up, and throw you on the ground.  When picking you up, luckily they can't harm you with any thinner or electros. It is selected as one of the new enemies in Epic Mickey 3: Brothers in Arms.
