The What-Iffer (also spelt What-Ifer, or Whatiffer) is a magical glowing orb that, when someone asks, "What if [question]?", will create a scenario inside of themself pertaining to that question.
They are a shiny, glowing orb that is coloured with a yellow to pink gradient. They can sometimes have a curve resembling a question mark above them.
Personality[]
When a Numberblock asks a question that starts with "What if-," the What-Iffer will appear and imagine a universe in which the question has already occurred; in which the question gets explained or solved. (As seen in the episodes What If? and Twoland.)
The What-Iffer themself can also imagine different dimensions inside themself. (as shown in Twoland as well.)
Trivia[]
They and Zero are the only characters without a complete face, although Zero only has a mouth.
They only appeared twice in Numberblocks Series 5: their debut in Twoland, and their return in What If?
