I would create a sprite that has several different animation frames. Frame 0 could be a sponge, frame 1 a television and frame 2 a water balloon.
I would give the sprite platformer behavior. When you want to spawn an instance of that puck in the bottom center of the screen, you would give it a random x velocity from maybe -100 to 100. Then give it a Y velocity of -600 to -800 for example so it will pop up and then fall down. You would also choose which frame would be showing to represent which object you want.
Platformer isn't necessarily designed for this because it has in mind that you would be controlling the "sprite" with the arrow keys or something. But I find that it's the easiest to manipulate still compared to physics which will have a lot of junk you don't need for a simple object being tossed up in the air and falling down. Doesn't sound you'll be wanting objects to collide or anything cause they didn't in the original game.
