They resemble four-legged octopuses with a hole at the top to catch stars to eat. Starcatchers rely on Golden Guppies to drop stars so they can eat. They dwell at the bottom of the tank to move around. In Adventure Mode, you can buy a Starcatcher in Tank 2 that costs $750. Once they catch a star, they throw a diamond worth $200. In Virtual Tank, sometimes a Starcatcher will appear in the store costing 2500 shells. They must eat 3 stars each time to toss a blue conch worth 5 shells.
