"Hamtaro" is an English-language adaptation of the 2000 series "Tottoko Hamtaro" ("Hamtaro the Hamster"). With his outsized round head, huge eyes, big ears, and tiny limbs, Hamtaro is another aggressively cute little character in the tradition of Hello Kitty and Pikachu. In "Hamtaro, Please Come Home," his owner Laura and her parents move into a new house in the suburbs. While they're unpacking, Hamtaro sneaks out to explore and starts making friends with other hamsters: nervous Oxnard, pushy Boss, and pretty Bijou. (The neighborhood is apparently overrun with the little rodents.) The episodes quickly fall into a pattern: Laura socializes with her new classmates--most of whom also have hamsters--while Hamtaro secretly meets his pals, the Ham-Hams, in their underground clubhouse. "Hamtaro" is a harmless entertainment for preschoolers, although their older siblings may dismiss it as saccharine and sappy. Unrated: suitable for all ages. "--Charles Solomon"
