After gathering many more Power Berries, the heroes are back in the Netherworld.
"We have to go back to the room where Betrayus was keeping the portal." Pac said.
The heroes find the portal room, but to their surprise, it's gone.
"Great, Betrayus must've guessed that we were gonna try to look in the same place it was the last time." Pac said.
"But we can't give up! If we're too late, Earth is doomed." Isabella said. "And it's not over yet, 'cause when the going gets tough, the tough get going."
"Now who's with me?" Isabella asks.
"Yeah!" The heroes all yell out.
"Who's with me?" Isabella asks.
"Yeah!" The heroes yell out.
"Judging by the lack of sound, I say they might already be at Earth, we better hurry." Ferb said.
"Then let's get searching." Pac said, and everyone fly around on their hover boards.
The heroes regroup after searching for a while. "We tried a whole bunch of places, but where's the portal?" Katie asked.
"Eh, don't worry, we know where it is." Blinky's voice is heard.
"Hey you guys, why are you still here?" Pac asked. "I thought Betrayus was gonna send every ghosts to Earth."
"Actually, after Betrayus found us, he didn't bother to untie us, so we got out ourselves, and by the time we were out, Betrayus and the other ghosts already left." Inky said.
Soon the heroes found the location of the portal back in the prison.
"I never thought we'd find the portal here." Gretchen said.
"Well, you guys go to Earth and do your things." Blinky said.
"Okay, thanks for your help." Milly said, and everyone heads into the portal.
The heroes arrived back to the Netherworld to find the portal. They finally find it with the help of the Ghost Gang. Can the heroes arrive back to Earth in time to stop Betrayus? To be continued...
