People were talking about this glitch where you put 2 or more kids on a mushroom or collectable and they all pick it up. Well, only 1 did, but the mushroom was still there. So i put another kid on it and the mushroom disappeared!

1) The game needs to be paused while you put all the kids on the mushroom (or other items).

2) Two kids never work for me either, same thing happens as happened to you. I usually only get results with 4 or more kids. Sometimes 3 will work, too.

I never got three to work.

Also, beware, DDashLuver, the item will disappear even while the game is paused if you take too long to gather/drop kids.

ya if u pauze the game for a very long time and come back after words... you can miss very rare items that may take a long time to come back to you.. so thats why i play as long as possible until i win..

Remember the tiki mask said" Whether your playing or not the game will still go on or something"

You have to make sure to pause with the spacebar as well. I've noticed that it will only work that way. If you try to pause with the menu, any items on the ground (both mushrooms and collectables) will disappear. Hope this helps.
