This article is about The Land Before Time character.For other uses, see Spike. Spike, the spike-tail (Stegosaurus), is a friend of Littlefoot in The Land Before Time film series. He is the 'mute' of the group, in terms that he hardly ever spoke. In The Land Before Time II: The Great Valley Adventure, his design was modified; he no longer had any small spikes on his tail. This is presumably to make him easier for the animators to draw, but compared to Cera's modification, Spike's isn't as drastic.
