There will be times the games tends to lag, this will cause the children in the village to simply stand and do nothing. This can be a blessing in disguise; those little feet can be fast and when you need a mushroom picked or item collected catching them can be a chore. When the lag occurs place each child in a different zone. Though they will stand and do nothing once a mushroom or items pops you have them close at hand to pick it. Also they will do this before returning to stand still, just move them back to the spot you want them in. This glitch is random throughout the game but when it happens make it useful.
