The WarpStone, despite living on a planet filled with dinosaurs, is infamously somehow incapable of warping them, hence why Tricky can't accompany Fox to Krazoa Palace.

In the Japanese version of Star Fox Adventures, the WarpStone, whose Japanese name is ワープ魔人 (Wāpu majin) ("majin" is a word to describe magical, often demonic beings), offers a different explanation of why he can't warp Tricky through Japanese subtitles:


Essentially, it's not that the WarpStone can't teleport dinosaurs like Tricky, it's just that they're merely afraid of being warped.
