Galago !

Galagos are small, nocturnal primates. Galagos have "bottle-brush" tails and very cute, large, dark eyes. Galagos eat both fruit and insects. Galagos are also critically endangered, mostly due to deforestation. I think galagos would be a very cute addition to Minecraft!

They would be a neutral mob and untamable, but they could interact with the player. A galago would spawn in the jungle biome, often be seen climbing vines, and when fed watermelon, will lead the player to a jungle temple if there is one nearby. This mechanic would work similarly to how dolphins lead the player to the nearest shipwreck or underwater ruin when fed cod.
