Orb (Super Paper Mario)

The Orbs in Super Paper Mario are items needed to make a bridge leading to Grambi's Castle. The three different orbs consist of the Yellow Orb, the Blue Orb and the Red Orb. These orbs are elliptical in shape compared to traditional orbs of the circular variety. All of these are obtained in Chapter 7-4 and after placing them all on a glowing pedestal, the bridge is made.

Yellow Orb
Mario and co., on the hunt for the Orbs, encountered Yebbi. He was hiding in a restroom, worried that a Skellobit was at the door. Mario and friends had to tell Yebbi that he was a monster, therefore Yebbi knew that a monster would never confess their real identity, and exited the restroom. Relieved, Yebbi gave Mario and friends the Yellow Orb.

Blue Orb
Mario and co. also encountered Blubi on their journey. When they found him, he was frozen. Bowser had to use his Fire Breath to melt the ice, freeing Blubi. However, when he woke up with amnesia, Mario and co. had to speak with him until he came back to his senses and gave Mario and company the Blue Orb.

Red Orb
Mario and co. encountered Rebbi on their journey. He was battling a horde of Skellobits and tiring due to the vast number of the creatures, instructed Mario and company to defeat them. After they are all defeated, Rebbi rewards Mario and friends with the Red Orb.
