To design the creatures of Terabithia, Csupó wanted to use "little more artsy, imaginative, fantastical creatures than the typical rendered characters you see in other movies." He was inspired by Terry Gilliam and Ridley Scott. Dima Malanitchev drew the creatures. Csupó helped him in this. Csupó chose Weta Digital render the 3D animation. He "was impressed with their artistic integrity, the teamwork, the [fact that] people were really nice, and also they responded to our designs very positively." Weta modified some of the creature designs. However, they mainly used Csupó's original designs.
