A somewhat strange platformer with a somewhat strange powerup system: the more damage you take, the more powerful you become. Released in Europe as The Trolls in Crazyland, a graphical hack featuring everyone's favorite naked plastic trolls. A US release by NTVIC, titled "Crazyland! The Ride Of Your Life!", was cancelled.

Enter the password Z!N* to display the message "PROGRAM BY N. KAWAMOTO" and start with 99 lives. The message was removed in the European version, but you still get the extra lives.

The same code can be found in one other KID game, Banana Prince, though it's completely unused there.

Disabled Stage Select

Press Left or Right to change the stage number (includes mid-stage checkpoints), B to reset the number to 00, and Start to start the game. You can also choose stage FE to view the first ending sequence, or stage FF to view the second.

Partial credit!

It seems that KID originally wanted to include their logo in the CHR, as with several of their previous games, but was forced to erase most of it due to lack of space.

Regional Differences



The European version adds a screen full of copyright information before the opening cutscene, while the Japanese version goes straight to the cutscene.

The title screen was redesigned for the European release, and as seen above, the copyright info was moved to a separate screen.

In the Japanese version, you play as a kid named Ponpon who kicks footballs. In the European version, you play as a Troll named Winky who kicks fireballs.

The music for the Space Ride stage was altered between releases. The echo was removed and the lead was moved from the triangle channel to the pulse channel.
