Thank you! Someone else had the same I idea as me. The rhino is most probably not going to happen, but a bull can work.

And red gorillas are welcome too. :)
I forgot those. Heck, we already had two looking back.

A red gorilla sounds perfect. I guess the red ranger might get an elephant, then anything could be possible.

Question: what if a zoo is a front for the base of operations?
I think it can fit well with the theme.
Or maybe a safari themed truck as the base.
They can probably travel around like Kakuranger or Go-onger.
