"Good Morning!" Uncle Grandpa greeted.
"You already said that!" Waluigi pointed out.
"I know, but since this is a new chapter, I might as well say it again!" Uncle Grandpa assumed. "After all, Brewster and Harold each have catch phrases they say in every chapter they're in." Uncle Grandpa turned around. "Anyway, you need my help, so follow me!" A laser beam came out of Belly Bag, which suddenly hit a nearby tree and opened up a portal. Giant Realistic Flying Tiger came out of the portal, a rainbow trail coming out behind her.
"Let's ride Realistic Flying Tiger out of this forest!" Uncle Grandpa announced, jumping onto the back of Giant Realistic Flying Tiger.
"Whatever. At least it beats being here." Waluigi floated up onto the back of Giant Realistic Flying Tiger, before Relicanth, Lilligant and Whimsicott got on as well.
"Wait, how fast is this tiger? I don't wanna get airsick!" Lilligant mentioned, holding on tight.
"Oh girl up, Lil!" Whimsicott put her stubby arm on Lilligant's shoulder.
Giant Realistic Flying Tiger growled back at Lilligant.
"Giant Realistic Flying Tiger doesn't like it when you refer to her as just a tiger." Uncle Grandpa stated. "And don't worry, riding on the back of Giant Realistic Flying Tiger will be fun!"
"I Relican't wait." Relicanth stated.
Suddenly, Giant Realistic Flying Tiger flew into the portal, leaving a rainbow trail behind her as the portal closed, the six of them going through a multicolored sky.
"Wait! We forgot about Lume!" Lilligant gasped.
"Don't worry about that!" Uncle Grandpa reached into Belly Bag, pulling Lume out of him.
"Where am I?" Lume asked.
"Outside of me, that's for sure." Belly Bag thought.
Suddenly, Emmet Brown also popped through Belly Bag's mouth. "Great Scott! This is beyond anything scientifically possible! Some sort of alternate dimension!"
Uncle Grandpa sighed, face palming himself. "Oh great, a scientist who will ruin my logic with his own."
