They first meet Scuttle, one of the Sand Creepers that denies some help from a volcano by Littlefoot using a log but the Sand Creeper jumped from an island that he was stranded on when the volcano was ozzing lava and landed on Cera's nose (making the Threehorn very angry, leaving Littlefoot to get her to calm down).
Meanwhile, as Crunch, Scuttle's former leader pinches Spike on the nose by using its claws as the 'Big Wise One' gives chase at him, the kids followed Scuttle to a watery place known as a whirlpool which he demands the kids to get some kelp for him to eat (which the kids think that Scuttle is in charge for them as slaves).
Cera, who has a dislike to the Sand Creeper and was nearly drowned in that whirlpool thinking that she wanted to try it out first, gets angry at the crab and tells him that he can be the leader of the rest of the Sand Creepers which it was a good idea and near the end, Scuttle becomes the leader of the Sand Creepers to take them back to their home while Spike gives another chase to Crunch who pinched the 'Big Wise One' once again.
- Scuttle the Sand Creeper (becomes as the new leader of the Sand Creepers)
- Crunch the former leader (who loves to pinch Spike on the nose)
