Play Kirby in Sonic the Hedgehog 2 Online

Summary

Kirby in Sonic the Hedgehog 2 is a quirky hack that swaps Sonic for Kirby and Waddle Dee as the playable heroes, pitting them against Dr. Robotnik. Kirby retains his classic inhale ability—he can swallow monitors and most foes, though he never gains their powers—while Waddle Dee simply runs and jumps. Health is tracked by a life counter, and the only way to refill it is by collecting over 50 rings, hitting lampposts, finding randomized 1‑Up monitors, or racking up 50,000‑point score milestones. The hack offers four difficulty settings: Beginner mirrors the original Sonic’s ring‑based lives, Easy and Normal use health‑based lives (with Normal adding random monitors), and Insane disables continues, removes lamppost 1‑Ups and demands 100+ rings for each extra life. A hidden Palace zone has been restored as a single‑act level tucked somewhere in Mystic Cave Act 2, giving Kirby fans a nostalgic secret to hunt.
