The Ruby Eye appears in battle in groups of two or three. It is the dark form of Orange Float Several of these guard the main path leading to the back area of the Catacombs and must be fought in order to proceed forward.
The normal attack is a butting attack on all characters grouped closed together. Overrun is a piercing attack in which it charges through a character or characters in a line, with a chance of knockdown. It can also use Cannon Shell to drop a bomb on a character or characters standing behind it. Finally, it can use Cheer to heal an ally.
The Ruby Eye uses a similar attack set to its Ruby Eye counterpart, but has lower strength and defense, making it the less dangerous opponent. The charging Overrun attack can deal a lot of damage, particularly if it then runs up on a character and attacks them from behind. Besides the lower overall power, the only major difference between it and the Orange Float is that it possesses a healing skill.
- The Ruby Eye/Orange Float is the only light/dark enemy combination that morphs between two different forms that are palette swaps of each other.
