Obtuse is a greenish-grey PacWorlder seen in "Heebo-Skeebo" when he uses Skeebo to steal Pac-Man's Power Berries but he fails when Skeebo ate the power berries. He then last appeared when he sees Skeebo fly to the Netherworld, much to his delight. It is unknown what happened to Obtuse afterwards, but he might have been defeated by Pac-Man and his pals or he might even be arrested. He is nearly immune to ghost slime. He was working for Betrayus.
