Coming to a halt as the fur starts to slope more precariously downward, Benjiro peers down and sees the tail trailing. A look around at the back end is confirmation as he recognizes the relatively lower slopes as familiar to seeing Bunsen stretch out on his belly at home.

Looks like he might follow the tail from here. To do that, he has to get down, so he searches for a ledge he might be able to jump to along the cavern wall down lower or to the sides.
