When Gumball and Darwin got home, they opened the invitation that Tobias gave them. "You're invited to Tobias's birthday party," Gumball read.

"Saturday, January 12 at 1:00," Darwin continued.

"Should we go?" Gumball asked.

"We should!" Darwin smiled.

"We have to ask Mom first," said Gumball.

"I'm okay with that," said Darwin.
