“The final four monsters always win. Even the ultimate masters are sent down to defeat. Prepare your excuse for losing!”
Dedar is the fifteenth boss that Toad faces in VS COM mode of the SNES version of Wario's Woods. She is found in Wario's castle. Dedar is a short green elf-like creature with red clothes and long pointy ears. Dedar is so confident in her abilities that she suggests Toad should plan on having some excuses for losing. After being defeated by Toad, Dedar herself is seen trying to think of an excuse of her own.
