Frog Fractions 2 was a Kickstarter campaign for a mysterious sequel to the satirical browser game Frog Fractions, where the game would be hidden inside another, unrelated title with no announcement. Backers would only receive codes for the game once Frog Fractions fans managed to discover the game's identity, with many bizarre and highly cryptic clues being given until the game's discovery, unravelling a surreal story about time travelers and alternate universes involving fake websites and files stored on them, as well as physical appearances and merchandise.

Two years after the Kickstarter was funded, the game was discovered within the game Glittermitten Grove. Frog Fractions creator Jim Crawford would later state that he believed the Glittermitten Grove Easter egg to not be Frog Fractions 2, but rather Frog Fractions 3, with the ARG to locate the game being the second installment in the franchise.
