The Adventures of Ook and Gluk Jr.: Kung-Fu Cavekids in Outer Space

The Adventures of Ook and Gluk Jr: Kung-Fu Cavekids in Outer Space is a possible upcoming sequel to The Adventures of Ook and Gluk: Kung-Fu Cavemen From The Future.

It was teased to be "coming soon-ish" on the last page of its predecessor, although no release date has been announced. Since the book has been in development hell for several years, there have been rumors that it was cancelled. Although, nothing was officially confirmed. Due to the first book being removed from publication, it is likely that it is cancelled.

The book would star Ook Shadowski, Lan Wong (who is now named Lan Schadowski), Gluk Jones, Gak Shadowski (who is now named Gak Jones), Lily (who now resembles Mog-Mog), and their children. The children would be sent to outer space on a rocket, fighting against aliens.
