The Pogo-Dozers are a modification for Romeo's Laboratory that enables Romeo to punch hard surfaces such as walls to break into wherever he wants. It was used in an attempt to break into the Museum.
The Pogo Dozers consist of large red boxing gloves with large robotic arms attached with springs. They were attached to the side of Romeo's mobile laboratory.
After discovering the springs, the PJ Masks used them as pogo-sticks, hence the name. Interestingly, Romeo started calling the Pogo dozers as such, too, after the PJ Masks coined the term. Romeo only referred to it as bulldozer before.
