From the Super Mario Wiki
“Whuzzat? Space Byway? Oog... Haven't seen one... Haven't eaten one either...”
Blarfle is a young Blobule in Super Paper Mario. When first talked to, he says to relax and to not worry about time, his reasoning being that space is endless. After Super Dimentio is defeated, he thanks the Heroes of Light for saving all worlds. Inside his house is an invisible Coin Block.
This young man is Blarfle... He's a strapping young Blobule... He never leaves this star, but drives his thoughts to the endless space...
