Kingdom Hearts 3D: Dream Drop Distance
The Kaeru Ouji is a secret boss that Sora and Riku encounter in several worlds. When first encountered, the Kaeru Ouji will ask for a fight. Upon accepting his challenge, the Kaeru Ouji will attack and summon Chef Kyroos and Kaeru Soldiers to aid him in battle. The Kaeru Ouji has a lot of hit points, and when the player depletes enough of the Kaeru Ouji's overall health, he'll retreat and blow the player a kiss, and the player must find him elsewhere to continue fighting him.
