yes! pandas are definitely on the more extreme end of this, but bears in general do a weird almost-marsupial thing where the babies come out RIDICULOUSLY undercooked, and have to spend one to three solid months in the den with mom before they’re baked through enough to toddle outside!
but they’re perfectly photogenic by that point, of course. so who cares.
in other words: BEAR LARVA.
This is likely why Pliny and Aelian described bear cubs being born as shapeless lumps, which the parent then licks into shape.
Medieval accounts turned it into a moral lesson – we have to be metaphorically licked into shape by our parents to become upstanding adults.
