Go to Snowman's Land as Mario and go up the big snowman. Allow the big snowman blow you off, then pick up the crate by the ice cubes. Go to the little snowman with the Mario cap (while carrying the crate) and throw the crate at the little snowman to make the Mario cap come off the little snowman. Keep doing this so more caps keep appearing each time . Note: This only works as Mario and doesn’t always work.
