The Blockston Dogmatics is a pet introduced with the 15.3.0 update.
It has a yellow body and thighs and grey legs. It somewhat resembles the AT-AT from Star Wars. It has a turret on top with a blue accent where it attacks, the turret on Blockston could be a possible head. Unlike a dog, it has no tail, and a panel thingy in front.

The pet and it’s name are a parody on Boston Dynamics’ robot dog.
