Play Big's Fishing Derby Online

Summary

Big's Fishing Derby is a quirky total‑conversion of Sonic the Hedgehog 2 that swaps high‑speed platforming for a wacky fishing showdown. You control Big, who’s on a mission to reel in a mischievous frog that’s swallowed an emerald, while Dr. Robotnik lurks nearby with his own line, hoping to snag the critter and claim all the Chaos Emeralds. The gameplay flips the classic Sonic levels into watery arenas where timing and angle matter more than speed, turning familiar backdrops into splash‑filled battlegrounds. Every successful catch not only protects the emerald‑laden frog but also keeps Robotnik’s plans at bay, making each round feel like a frantic tug‑of‑war between hero and villain.

Storyline

In Big's Fishing Derby, Froggy leaps into a warp ring and somehow gathers all the Chaos Emeralds. The surge of emerald energy powers Dr. Robotnik’s aquatic roboticizer. Robotnik, monitoring the readings, realizes the emeralds are nearby and decides to embark on a fishing trip to retrieve them.

Meanwhile, Big is determined to rescue his pet frog, but when he spots Robotnik he suspects the doctor is after something valuable. Believing Froggy holds the key, Big resolves to keep whatever it is out of Robotnik’s grasp.
