Spikies are the only living enemies to appear in the BOXBOY! series.
Spikies are black circles surrounded by spikes on the top with wave-like bottom.
Spiky once again returns in BYE-BYE BOXBOY!, and this time they have a new ability. They are able to crawl on the background, and thus do not need to be touching the ground to move. This ability opens the Spiky mechanic up to new possibilities and puzzles within the game. They begin appearing in the game's 14th World Those Nesting Within.
