The Amazing Hatching Egg / Growing Dinosaur thingy!

Yes, folks, it's the Amazing Hatching-Egg-Growing-Dinosaur thingy! Or the Amazing Hatching-a-Growing-Dinosaur-Egg or the Egg-that-Hatches-an-Amazing-Growing...ah, you get the idea. You put the egg in water for a day and an "amazing" dinosaur breaks out of it (or is it the egg that's amazing?). Put said dino in a new jar of water and watch it continue to grow! IN the B-movie version, you keep transferring it to bigger containers until you finally put it in the back of a pickup and drive to the beach where you unload the monster into the ocean. It grows so large it threatens to destroy the world. And YOU'RE to blame!!!
