Hamtaro S01 E52 It's Robin-Ham!

"Little Hamsters, Big Adventures."

Snoozer sleeps so peacefully that no Ham would know how busy his dreams are. In one dream, the Ham-Hams are in a castle town and Robin Ham (played by Hamtaro) is going to Chick-ah Chick-ah Castle to visit the sick father of Maid Laurien.
