Katsuyu  

, カツユ

Katsuyu, the summon of Tsunade, is known as the slug queen. In comparison to Gamabunta and Manda, who are Jiraiya's and Orochimaru's respective summons, Katsuyu is more submissive and less talkative than her counterparts. Katsuyu has a unique ability called Slug Great Division which allows her to split into smaller slugs for evasion purposes or to perform small tasks. She can also spit acid with her Tongue Tooth Sticky Acid, an attack strong enough to melt through solid rock.
