Everyone else mentions that they have something else to do: Luna is going skiing with Sam, Luan has a gig at Sunset Canyon Retirement Home, and Lynn Sr. and Rita plan to take everyone else to Miami Beach, Florida.

He gets a package that turns out to be a 13-person toboggan to use on Tall Timbers Hill and opens it in front of his family only to find that it broke during the delivery.

They make Lori homesick, fool Luna into thinking that Mick wants to jam with her, build a Sharkodile out of Clyde's family's film props, and disguise themselves as elderly people at the Sunset Canyon Retirement Home to pull off pranks enough for Pop-Pop to cancel Luan's gig.

Later on, while getting ready for the tree-lighting ceremony, Lincoln finds that he only made things worse for the family, having accidentally sprayed Lisa's custom-built Sharkodile repellent on Lynn Sr. causing him to not see straight, lose balance, and have unintelligible speech.

As Rita goes to pick up a stranded Lori and Bobby, Lincoln tries to call Katherine Mulligan and tell her that the creature isn't real, but she believes that he's pranking her.
