Friday Night Funkin Cartoon Blob is a free online rhythm game available at fnf.gosprunki.net. This fan-made FNF mod delivers an original storyline created by a developer who hasn't played the base game, resulting in a unique universe. In this mod, Cartoon Cat and Cartoon Dog merge to form a mysterious blob creature. They also encounter a mutated crocodile with one eye on top of its head and one on the bottom. Boyfriend transforms into a cartoon form while retaining full body control and the ability to change his appearance (though he chooses not to use it in-game). The Cartoon Blob attempts to merge with BF, but BF refuses. The creator plans to add a death animation where the blob consumes BF and sprouts additional eyes and a mouth.
