She flies over to the planet, passes through the gravitational force that neither Super Sonic nor Super Shadow could pass through, and plants herself on top of it. She then becomes a tree, saying that she has now immobilized Dark Oak. She tells Tails to load and fire the Sonic Driver and shoot it at the planet. Everyone is shocked and does not know whether or not to risk saving the galaxy if they're going to kill Cosmo in the process. Tails, however, is very hesitant, but Cosmo re-assures him that her seeds will be spread throughout the galaxy (English dub only).
