Giantess Sammie wakes up with a terrible tooth ache. It's so bad she rushes to the mirror to take a better look and thinks she may have a cavity but it's hard for her to see. She needs the help of some one tiny and she knows exactly who to call. She invites her shrunken friend over to take a look in her mouth and see if he can use his tiny body to find what's causing her pain. But once he's in there, will he make it out or will he be swallowed?
