Clifford discovers a loose tooth! It wiggles, and wobbles, and worries him. Emily Elizabeth reassures him that it will fall out and be replaced by a bigger tooth. And the tooth fairy will come take away the old tooth and leave a treat in its place. Clifford and his friends decide to help the tooth come out early so Clifford can get his treat sooner. Their suggestions get wilder and wilder: pulling the tooth out, sneezing it out, and chewing lots and lots of bubble gum. But Clifford discovers that sometimes the best things come to those who wait.
