How do you make a character bounce?

I want to make a game kinda like this one (I used to play it when I was a kid)
http://games.disney.com/disneychannel-fish-hooks-freshwater-bounce

the kind where you use your mouse to control a bouncing character.

I've drawn all my characters, props and backgrounds...
The problem is...I can't get my actor to bounce! It's supposed to look something like this: http://arcade.gamesalad.com/games/127254

but instead of the arrow keys I want to use the mouse to control the character.

How do I do it?

guys it's my first time using gamesalad don't make fun of me... I do art, not game-building!

but it's fun tho

I've made a bunch of chibi sprites and I'm using them as characters cuz I want the game to look pixelly and cute.

Thanks for your help!
