I’ve spent far too much time pondering the taxonomic classification of furbies. Like, starting from the assumption that they’re mammals, the closest match would be monotreme. But monotremes do not have anywhere close to that level of ear development. So I can only conclude that they’re a unique order of mammal that split off from monotremes around the same time as marsupials, developing more advanced ears but retaining the beak and oviparous reproduction.

Also, their forward-facing eyes are a clear indication that they are predators, and the lack of forelimbs suggests a hunting style similar to carnotaurus.
