After a few seconds, the group reaches the nearby waterfall. They go on a bridge, and look around. "Where the hell is he..." Sonic thinks. Suddenly, from behind the waterfall, the machine comes. Inside the machine, is non-other than Doctor Eggman. "OH,HO,HO,HO,HO!" Eggman laughs. Sonic looks up, and sees Eggman. "Eggman! Why did you destroy this beautiful island!" Sonic exclaims. Eggman just smirks at Sonic. "Don't you mean, why did YOU destroy the island Sonic?" Eggman asks evilly. Rainbow Dash flies up to the cockpit. "No way! Sonic would never do this!" RD exclaims. Eggman just ignors Rainbow Dash, and rams her towards the waterfall, then, he shoots the bridge the other heroes are on with fire balls. "Look out!" Tails exclaims. The heroes quickly run off the bridge, before the fire balls set in ablaze, and destroy it. Eggman then fades back int the waterfall, completely forgetting that he rammed Rainbow Dash into it. When Eggman goes into the waterfall, he is met by an EXTREMELY pissed Rainbow Dash. "SON OF A BITCH!" Eggman yells. Rainbow Dash flies at the machine, and sends it out of the waterfall, and into the sight of the other heroes.

She flies out of the waterfall, and lands near Sonic and company. "Ram me into a waterfall will you?! YOUR GONNA GET YOUR ASS KICKED!" RD yells. Before Rainbow Dash can charge at Eggman, the machine Eggman's in sends out a barrage of fireballs at the heroes. They are quickly avoided, and Sonic jumps up at the machine. Sonic almost feels like he homed into it. Sonic lands a hit on the machine, and goes back to the ground. The machine starts to spark. "Not so tough are ya?" RD asks cockily, even though it is still clear she's still pissed at Eggman. "Why you nasty little pincushions!" Eggman exclaims. Eggman fades back into the waterfall, and starts to shoot fireballs from behind it. This weirds out Tails and Twilight. "That defies laws of physics..." Tails whispers, close to spazzing out. The two brainiacs just stand in the way of the fireballs, still freaked about the fireballs against the waterfall. Sonic sees this, and sighs. "DAMMIT TAILS!" Sonic yells. Sonic runs over to the two brainiacs, and grabs them just as they are about to be scorched by fireballs. Sonic sets them down by the side the heroes came. "Stay here. Me and Dash got this." Sonic says. Tails and Twilight slowly nod their heads, and Sonic heads back to the battlefield.

Sonic looks around, and sees Rainbow Dash, or Eggman are nowhere to be found. That's when, a voice calls out from behind the waterfall. "Sonic! Catch!" the voice exclaims. Suddenly, Eggman's machine pops out of the waterfall, quickly followed by Rainbow Dash. Before Eggman can regain control of his machine, Sonic spin jumps into it, cutting the machine in half. Before the machine explodes, Eggman presses the eject button on it, and falls down the waterfall with his Egg Mobile. Sonic looks over the edge, and sees the long drop. "Have a nice fall!" Sonic yells out into the pit. Then, a bridge appears on the other side of the casam. Along with that, a metal capsule appears in the middle of the platform the heroes are on. "Another capsule. This better not be a trap..." Sonic says, sighing. Sonic jumps on the capsule, and presses the yellow release button on it. The capsule opens up, releasing small animals. The animals go away, and Sonic jumps off the capsule. "Phew..." Sonic whispers. Then, the group of heroes go on the other bridge, and see a dead end. "A dead end? Who thought of putting a bridge here then?" Tails asks. That's when, a familiar laughter is heard. Sonic looks up, and sees the red echidna from earlier. "Who are you!" Sonic exclaims, clenching his fist. The red echidna just smiles. "My name is Knuckles. And you're about to all fall." The echidna says. Suddenly, a button appears in front of Knuckles, and Knuckles presses it. The button causes the bridge to collapse, and the heroes to fall into the same casam.
