While Kipo may be able to navigate the tunnels in her jaguar form, the better question might be if she'd want to: while a couple of the rooms are large enough that she'd have some space to navigate, many of the rooms are the size of what you'd find in a standard house and some of the hallways may feel cramped. Factoring in any furniture or equipment that may be around, it might be too difficult to navigate beyond the rooms nearest the entrance in jaguar form.

Kipo can absolutely break stuff that she finds in the lab. But beware; there are chemicals in flasks that may not mix well! Smashing everything indiscriminately may result in fire, noxious gases, or other effects that may go beyond what she intended...
