ZhuZhu Pets Manga

Here's a post from the official Japanese ZhuZhu Pets blog, confirming a manga appeared in a June 2010 issue of Pucchigumi.

This is a photo of a page showing a ZhuZhu Pets manga called "Yahoo!! Hamster Life: ZhuZhu Pets School" (いやっほぅ!! ハムスターライフ: ズーズーペットスクール), featuring Num Nums (ナムナム), Pipsqueak (her Japanese name, ピップス, is "Pips" in English), Jilly (ジリー), and Mr. Squiggles (Mr. スクイーグル). This was from the June 2010 issue of a Pucchigumi magazine, which was published on the 15th of May that year.

The manga was illustrated by Yumi Tsukirino. I don't know how many comics there were, but weirdly, a website description for the 2010 October issue on neowing.co.jp (alternative link) mentions the name of the manga. That issue was released on the 15th of September that year.
