Perhaps you placed the Heaven Statue and played the Grass Whistle to call rain? Its icon is just a generic placeholder which appears many times among the item sprites. Grass Whistle - This enigmatic item is listed between the Heaven Statue and the Dog Whistle in the game's data, so it probably worked with one of those items.Its icon is the same as the Sleepless Seal. Or it could've been yet another town progression item. Its description says that it's 'Used to summon rainfall', which suggests that it may have once been intended as an item in a puzzle. Heaven Statue - This item is rather interesting.In all likelihood, it was another of many items needed to help a town. Carrot - 'A carrot' is the only description this item has.It's possible they could have been another healing item, or one of many 'quest' items needed to help a town improve. Aloe Leaves - The description states that they're 'Leaves from an aloe plant'.None of them have any effect in-game, however. For instance, use Pro Action Replay (PAR) code 7F8000? (where '?' is one of the numbers listed below) to put that item in the first slot of your inventory. There are a number of items in the game which can only be obtained by hacking.
