In Kirby super star ultra are the great cave offensive treasures all in Kirby games only?

The Great Cave Offensive is a game in Kirby Super Star Ultra. The instruction manual says that the object of the game is to get all 60 treasures and make it out of the cave, but you don't have to get all 60 treasures. They just give you extra points. There are 4 areas in the cave: Sub-tree Area, Crystal, Lost Tower, and Garden. They each have a boss that you have to battle before you get to the next area. The 1st boss is Fatty Whale, the Crystal boss is Computer Virus, I think the Lost Tower Boss is Chameleo Arm, and the Garden boss (the final boss) is Wham Bam Rock.
