These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Even Better Sequel: Indeed, one of the main complaints about the first movie was the lack of focus and no real antagonist. This one addresses both by giving the lead to Chuckie and a much more relateable story for both parents and children. As well as making Coco a worthy villain for the film to focus on.
Moral Event Horizon: Coco and Jean-Claude cross this when they're willing to lock children away in a warehouse for the sake of a perfect wedding.
Jean-Claude pilots the Super Escargot mecha against the babies' Reptar mecha and attempts to destroy it, knowing full-well the babies are inside and even gleefully going along with it.
Toy Ship: As this is Kimi's introduction, this is also where shipping her with Tommy got started, particularly from the scene where they're watching the stage show and Kira places Kimi in Tommy's seat with him.
Tear Jerker: The scene where Chuckie is left out of the dance for all the kids and their mothers. It only makes it worse when Chuckie tells Angelica his wish for the bobfather game is to have a mother, only for her to tell him that they're no longer playing that game. Add to the fact that Sinead O' Connor's "When You Love" plays in the background.
When Chuckie and Kimi dance with their new parents, Kira and Chaz, respectively.
The scene on the airplane where Chuckie sees all of his friends happy with their respective mothers, and then stares longingly out the window and sees clouds that look like him and his mother together. The fact that "I Want A Mom That Will Last Forever" by Cyndi Lauper doesn't help.
