Fun items serve as attractions in a player's cafe. Some of these items are buyable from the decoration tab, while some are exclusively awarded from quests. Most fun items are unlocked at level 12.
"Charging" Fun Items
Fun items need to be charged every few hours in order to keep entertaining your customers. Unlike Exclusive Counters that require a heart to recharge, fun items can be recharged only by clicking, and entirely free of charge. Recharging the fun items give a small amount of XP, however, not charging fun items aren't known to have adverse effects on your cafe.
Alternatively, a user may use a battery special cafe kit in order to make their fun items' charge last twice as long.
