Wumpa Trees are found on N. Sanity Island in Crash Twinsanity. For their growth, Crash must find a very large plant seed resembling an acorn and roll the seed into the wumpa tree's burrow. Moments afterwards it will blossom into a very large, colorful, tree that produces Wumpa Fruit. During the game Farmer Ernest requests that Crash and Cortex get rid of the greedy worms so that his wumpa trees could grow, and if done in the allowed amount of time, the trees would sprout where the worms were buried.
- They are similar to palm trees.
