The main Wool Alien shown as drawn by Mine Yoshizaki.
|Species / Type||Wool Alien|
|Occupation||Ally to the Keron Army|
The Wool Planet (ウール惑星 Ūru wakusei) is a planet featured in Volume 25 of the manga.
According to Giroro, the Wool Planet's inhabitants are very peaceful and don't like to fight to much. They are considered allies of the Keron Army though and they are known for their fluffy wool. The wool has demonstrated to be very tough and sturdy against anything making it the best armor one can get.
The Wool Aliens are peaceful and quite gentle usually, though Kururu states that they greet each other with rather strong headbutts, enough to knock Shin Keroro several feet away. If the wool alien leaves their planet, their wool supply will gradually decrease until they are left bare. The Female wool alien also compares her people's wool to Pekopon's cotton.
