Toy Story 2: Buzz Lightyear to the Rescue!/Andy's House

Andy's Room
You start out in Andy's room. As a review of controls, press to jump,  to fire a laser, and  to aim your laser. When aiming, you can press and your laser will auto-aim to your closest enemy.

Start out by destroying the enemies, to cause them to drop coins. These coins are important, but disappear quickly, and need to be grabbed soon after they're dropped. After this, jump on the box then double-jump (press in mid air) on to the chair. Continue onto the desk, and turn around to see a platform with a cube spining in the air. Jump to it, walk underneath the cube and jump. This cube will give you good advice.

Push the board down this will form a ramp, climb up the ramp and jump on to the bed. The enemies have returned, but won't provide any more coins and can be ignored. From the bed, you will see a stand with another cube. Double-jump to it, and jump into the cube and follow its instructions.

When on the dresser, go over to the pipe, you can shimmy up by going up to it and moving upward. Jump on to the shelves and enter the cube located there; it will show you a zip-line. Jump onto the zip-line and slide down to the crib. Jump in the crib, collect the weird green coin, and do what the cube says.
