If you are quick enough and use the pause you can triple the collectables and shrooms.
First pause the game, then drop a kid on the collectable. Then drag two more kids close to said collectable while still paused. Pick up kid two while still paused. Hit the space bar to un-pause the almost immediately drop kid two on the collectable. Next quickly go to kid three and drag and drop him on the collectable.
