Tonic Trouble (1999)

Developed as a precursor to Rayman 2: The Great Escape, Tonic Trouble serves as an early showcase for Ubisoft’s 3D engine technology.
Plot and Setting:
The story begins on the spaceship Albatross, where Ed accidentally spills a highly reactive liquid that falls to Earth. The "tonic" causes chaotic mutations: tomatoes riot, carrots bite back, and a drunken Viking named Grögh becomes an all-powerful dictator. Ed is sentenced by an alien court to fix the disaster. Upon crashing on Earth, he teams up with a mad scientist named Doc and his daughter Suzy to build a machine capable of reaching Grögh's castle.
Gameplay Mechanics:
Abilities and Gadgets: Ed acquires numerous inventions from Doc to progress, including a peashooter for first-person combat, a pogo stick for traversing hazardous terrain, a bow tie for flying, and a diving helmet for underwater exploration.
Super Ed: By consuming popcorn from dispensers found in the levels, Ed can temporarily transform into "Super Ed," granting him increased strength to punch enemies and manipulate heavy objects.
Collectibles: Players must scour 12 distinct worlds for parts to Doc's machine, as well as thermometers to increase health and "antidotes" (mercury-like drops) to heal.
Versions and Legacy:
The game is notable for its distinct differences between platforms:
PC Version: Featured high-quality FMV cutscenes and was one of the first games optimized for the Intel Pentium II processor.
Nintendo 64 Version: Adjusted the opening sequence and certain level elements due to hardware limitations.
Branding: In a unique marketing move, the game featured real-world product placements that varied by region; the North American PC version featured Newman's Own popcorn, while European versions used Nestlé Crunch or Lion bars.
Despite mixed critical reviews regarding its controls and camera, it remains a cult classic for its surreal humor and its role in the development history of the Rayman franchise.
