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.
