Knights and Bikes

In the harbour area you'll find 4 pretty obvious spots with a sign for "Dry Shrimps". One is right next to where you enter the town, two of them can be found in the South-Western part and the final one to the East part of the harbour right before you go up the ramp. You need to water the shrimp to grow, which for tree of the spots can be done by kicking the puddle of water next to it. There's a single one which doesn’t have a puddle next to it for which you'll need the ability for Nessa to throw water-balloons. You'll automatically obtain this ability in the Theme Park as part of the story. For a visual aid on how to obtain this trophy, please refer to my video below:
