The Whoa Zone is 4-4, an area in Super Paper Mario. The fifth pure heart is found here. In the Whoa Zone, you can walk on the walls and ceiling, thanks to some gravity changing blocks. After venturing to the end of it, Mario and Co. find Squirps in a room with a statue of Squirps' mother. He then reveals his reasons for leading the group all the way here. He gives Mario and Co. the Pure Heart, but before the group can grab it, Mr. L appears and takes it, prompting Mario and Co. to give chase. They fight him, and defeat him. But then he brings out his robot "brother," Brobot. Mario and Co. defeat it too, and get the Pure Heart back. Squirps then thanks them for help, and falls asleep of weariness.
