Aranhaschimmia is the home planet of the Arachnichimps.


From space, Aranhaschimmia is a lime green planet with darker green marks.

Aranhaschimmia is full of forests and many predators.

It is a dangerous planet, which is why Arachnichimps only live at the tree tops, as their species is considered a delicacy to predators such as the Root Sharks.

It is always dark below the canopy on Aranhaschimmia.


It never snows naturally on Aranhaschimmia.
