You're a little yellow blockhead and you want to stay that way. Avoid the other blockheads who will splatter you with their color. Collect the jars of paint to restore your yellow color. Collect the jars of molasses to slow the other blockheads down. Pick up the shield to be invincible for a time. Avoid the Boss at all costs. Neither the shield or molasses affects him. Stay yellow for as long as you can.
