Dialoe is a Dimetrodon animatronic, who was intended for the FNaF 2 pizzeria, but was scrapped, likely for security/safety reasons.
Dialoe has the shape of a JW:TG Dimetrodon. Most of his body is painted in a light blue color, although his underbelly is marked with light grey. Faint, black splotches are limited to the light blue parts of his body. Meanwhile, the sail is a mix of a bright gold and orange.
Dialoe, originally designed as a cleaner bot, is dedicated to his job while he's working. Wether in service or not, he has a short temper and tends to throw a quick hissy fit when disturbed. This may be the reason why he was scrapped, as he got physical if he was provoked too much.
