New dog is the first scene before the intro starts in Asdfmovie3.
It also appears in the "Mine Turtle" song.
Dua Lipa: Hey girl, look at my new dog!
Kim: (looks down) Oh yeah, that's pretty cool— (there is nothing at Dua Lipa's feet) AWWW...! There's no dog there.
Dua Lipa: OOOOOOOOOORGH!!!!!
In "Mine Turtle"s song
Man 1 points at his feet and man 2 looks down to see a Mine turtle under Man 1's foot which explodes.
