Perhaps you have met this plant's little cousin, the Super Mario Piranha Plant Hand Puppet? These two are very similar in demeanor. They're good with kids and pets but not so much delivery workers, electricians, or plumbers.

Which is good because this embiggened puppet could probably swallow our former office corgi Rolo whole. (Imagine the little guy with a puppet twice that size.) Give this fearsome Super Mario baddie a spot in your personal greenhouse. This puppet version needs only your hand to thrive - no water or food. But maybe don’t wear overalls around it, just to be on the safe side.

If you’re not so much into a Piranha Plant, maybe a Donkey Kong will do for you?
