Happy Aquarium: What's inside those Mystery Treasure Chests?
My Mystery Treasure Chest Results:
4 x Octopus; costs 145 Coins at the store; resells for 116 Coins
4 x "Beware" Signs; costs 150 Coins at the store; resells for 120 Coins
4 x Glacier Point; costs 153 Coins at the store; resells for 122 Coins
4 x Bonsai; costs 154 Coins at the store; resells for 123 Coins
Since I sold back everything, I had spent 1,600 Coins, but got back 1,924 Coins. If you've got the patience to wait, the Chests could be a good monetary investment, because it's like it's guaranteed that you'll more than break even. But the whole point of the Chests is to get a random assortment of items, and the item selection was oddly consistent.
My Verdict: For 100 Coins, you can't expect too much. You'll get your money's worth and then some, but that's not the point of these grab-bag deals. They seriously need to grind some Gremlins into their randomizer to liven up the results. At least the Chests look cool.
