Plot
Amy tries to rescue Sonic from the watery planet, but everyone else keeps her back, trying to come up with another plan. Then, Knuckles comes up with a brilliant idea: use the Master Emerald to cut off the energy supply to Dark Oak. The team charges up the Sonic Power Cannon with the Master Emerald and fires it at Black Narcissus and Pale Bayleaf, destroying them. Unfortunately, after this is done, the Master Emerald shatters, and it is revealed that the Metarex have sucked up all the Chaos Emeralds' energy.

Dark Oak's dragon head becomes extremely weak because of a hit from the Sonic Power Cannon, and finally ceases movement. The planet expands, taking Dark Oak along with it. Meanwhile, inside the planet, Sonic sees what happens after the Forestation Process is complete. He manages to fight a bunch of sand monsters and plant-like tentacles, only to find out he's fighting in a dream and Sonic runs at full speed. Suddenly, Amy spots Sonic inside the planet and jumps in to save him. As she crashes through the roots in the water to rescue, she is knocked unconscious. Sonic catches Amy and stares at her in awe. However, as Amy and Sonic are falling through the water, a strange sphere surrounds them, which protects them and heals them. Chris (who's on Hyper Tornado) rescues Sonic and Amy. Suddenly however, Dark Oak's begins planet condensing into a giant seed-like object.

Dubbing changes

 * In the English dub, 4Kids makes up some more stuff and pretends that Hertia is talking to Cosmo through her red amulet, saying the spirit of their people will live on.... In the original, Cosmo wonders whether Dark Oak hates every species in the universe or simply wants revenge for what Cosmo's mom did to Lucus and everyone else.
 * Charmy's dialogue during their attacks on the Final Mova is different between versions.
 * Six seconds cut of a shot of Shadow trying to hold back the three beasts and then bouncing backwards.
 * When Chris flashes back to Lindsey/Nelson, Tanaka/Ella, Chuck, Sam/Danny/Francis and Helen, all of them made some sort of vocal expression, but this does not happen in the English dub.
 * One of Chris' entire lines and part of Eggman's when he is operating at the Crimson Egg are completely muted.
 * One minute and thirteen seconds cut, When Sonic is running through the odd world inside the planet.
 * Six seconds cut of a still of Sonic leaping in the air in letterbox format.
 * Some mutations on characters' voices exist in the English dub.
 * In the original, Tails just says that Dark Oak absorbed all the last energy of the Chaos Emeralds. In the dub, Tails says that the Master Emerald's power has made him even stronger now.
