In my school we had a Logo-like PL where you controlled a kangaroo and a more complex one where you сontrolled a robot arm with an internal stack that worked on a rectangular array of items. I remember the robot blowing up when you triggered a logical error like going out of bounds or a stack over/underflow.

UPD: The PLs were called "Roo&Robby" and written by https://en.wikipedia.org/wiki/Mark_Sapir before he emigrated to the US.
