Objective: Defeat Dr. Eggman's Vine Viper.

Recommended Character: Any character, but Sonic's Homing Attack is useful.
Boss Phases & Strategy:
- Phase 1: Vine Swings & Ground Pounds
- Eggman's machine, a large robotic snake, will swing from vines above the arena, occasionally dropping down to perform a ground pound.
- Attack Opportunity: When the Vine Viper performs a ground pound, it will briefly expose its head or a glowing weak point on its back. Jump and attack it.
- Dodge Strategy: Watch for its shadow to predict where it will land for the ground pound. When it swings, stay on the ground or jump over its body as it passes.
- Phase 2: Projectile Spit & Vine Traps
- After a few hits, the Vine Viper will start spitting projectiles (often sticky goo or small bombs) from its mouth. It will also try to trap you with its vines.
- Attack Opportunity: The weak point remains the same. You'll need to dodge projectiles while waiting for the ground pound opportunity.
- Dodge Strategy: The projectiles can be jumped over or dodged by moving quickly. If caught by a vine, mash the jump button to break free.
- Phase 3: Enraged Swings & Multiple Attacks
- The Vine Viper becomes more aggressive, swinging faster and performing ground pounds more frequently. It might also combine projectile attacks with vine traps.
- Attack Opportunity: This phase requires precise timing. Wait for the ground pound, quickly hit the weak point, and immediately prepare to dodge.
- Dodge Strategy: Stay mobile. Use your character's abilities to your advantage (e.g., Tails' flight to stay above the fray, Knuckles' glide to quickly cross the arena).
Rewards: Defeating the Vine Viper clears Speed Jungle Zone and grants access to the next area. You'll also receive a score bonus.
