@Pacu Eh, Rainforest Life has sort of broadened its scope over the years, with the mongoose and now the sengi. They don't feel too out of place in the context of a zoo like London where geographical or taxonomical groupings are generally stuck to either way.
@Springbok Various bromeliads and the like, no animals. I've always thought it might be nice for a couple of the rarer poison dart frog species...
