Matthias 100% pulls pranks on his teammates - changing their sticks out for rubber ones, swapping their hockey puck for one with a firecracker inside, removing cork from the ref’s whistle, all the way up to methodically setting up silly tableaus using hockey trees with everyone’s equipment on them - and that’s only the pranks that he pulls that are hockey-related. A whole world of potential exists out there for pranks that are just generic and silly - changing ringtones, leaving bobbleheads in the lockers of rival teammates, and dying jerseys in weird colours; that time that the Scarecrowd skated out against the Armada with their only uniforms being the exact same colours as Nevada, forcing them back into their locker room to get ahold of their “away” jerseys? 

Yeah, Matthias might’ve had something to do with that >:D

It’s all in good fun, and in the name of making a little chaos. There are so many mechanical points of, if not failure, then points of absurdity in the SHL, and just poking lightly at one of those points can often yield pretty hilarious results.
