An "uninvisible" Carl.

Carl is Charlotte's imaginary friend introduced in the episode "Invisible". He was made "uninvisible" when two fiends sprayed "uninvisible" serum on him, which proved that he actually was real, but just invisible. Soon after, he drank the invisible potion and turned invisible again.
