This is a multituberculate. They were a big branch early on the mammalian tree, they had some really wonky teeth, and now they're all dead - which is a sob story shared by most of life on earth. They were named after the many bumps (tubercules) on their teeth, and there is (currently!) no evidence that multituberculates were obsessed with rutabagas, parsnips, carrots, yams, or potatoes.
The following are not real animals. They are good* puns.
*actually, let's be real - they're pretty great puns.
