Gotta love the stolen Pokémon sound effects and re-used music. Also, I could be wrong but isn't the English translation of the title "Rayman: The Sunshine and the Rain"?
Edit: Oh, and for anyone who hasn't noticed the stage graphics for level 2 are stolen from Speedy Gonzales: Los Gatos Bandidos for the SNES. (Which of course, was subject to that Sonic the Hedgehog hack)
