Tottoko Hamutaro: Norisuta Hai!
The Hamtaro short series started to show on Nicktoons on October 10, 2006. The reason the short series was shown on the channel was because that Hamtaro started to have high ratings around six months after the series premiered on Nicktoons. However, the ratings had problems, so the channel had to stop airing Norisuta Hai on March 31, 2007, making Hamtaro and Keroppi the only anime programs on Nicktoons until June 20, 2008.
