There is, unfortunately, no way to implement animated cutscenes into the original game. However,
Knytt Stories Advanced can do some stuff with timed cutscenes, subtitles, and whatnot.
If you really need the animation aspect in the game, then you can shift Juni into a wall where she will steadily wallswim up (acts like a timer).Have a custom object on the screen so that the cutscene plays while you're rising. See
here for more details.
EDIT: You're gonna have to ask Nifflas for the spritesheets, and they haven't been released. There are a bunch of sprite sheets
here made by the fanbase.
