Great Job
As always, you manage to impress greatly with smooth animation and a nice cartoony style.
Though I did notice that when you had the fish jump out the window, it looked like you had to just stop drawing once you got to the edge of the window, and there are 2 ways off the top of my head that can fix that and make it better.
Firstly, you could use 3 layers, the top being your fish guy, the middle being the wall he's jumping behind, and 3rd being the layer he moves to for the last of the frames, then just animate him up until he would be crossing over behind the hole, or just animate seperate parts of him on the right layer. Then you just have all the foreground and background stuff and it should work fine.
Or you could do the easier way which I think doesn't give you as much of a sense of accomplishement (And may not be possible if you use movieclips on wiggling backgrouns that aren't just blinking a little) All you'd need for this way is to unlock only the layers which have the character parts, and then turn on "Edit Multiple Frames" and erase the part along the line of the window rim.
But yeah, good job :3
