The puffer fish is the wild symbol and it can substitute for all the other symbols on the reels, except the crab scatter symbol and the anchor bonus symbol, to help you form as many winning combinations as possible. Furthermore, it offers the chance to win the slot's top payout of 3,000x if you can land five of them on a payline.
The crab is the scatter symbol and if you can land three or more of them anywhere on the reels you will trigger the free spins round. However, the slot doesn't offer any scatter payouts.
Bonus Features and Free Spins
If you can land the puffer fish wild symbol on the centre position of the third reel then he will puff up until he is full. He will then deflate and fly around the reels depositing up to six extra wilds. When he is done any new wins are re-evaluated and you could win some huge payouts.
Landing three or more of the crab scatter symbols anywhere on the reels triggers the Cash Crab Pick game. Landing 3, 4 or 5 crabs awards 1, 2 or 3 picks respectively and then you just need to pick from the crabs on the reels to receive a cash prize. One of the crabs may offer a special reward of 100x your bet.
Landing the anchor bonus symbol on reels 1, 3 and 5 simultaneously triggers Albert's Underwater Bonus. First you need to pick a route for Albert to swim along and he will pick up spin, wilds, multipliers and more air. When the air runs out the free spins begin with all the collected items. If you land a further three anchors then you will receive eight more free spins.
Wacky Waters offers a massive top payout of 3,000x if you can land five of the puffer fish wild symbols along a payline.
