Across
  1. 1. Little crunchy guys that like to curl into a C shape. Pretty tasty.
  2. 3. Sticky guy who likes to glue itself to ships and whales. SpongeBob says this in frustration. Not for eating.
  3. 4. Walks sideways and pinches things. Delicious.
  4. 7. Famously turns red when you cook it. Tastes wonderful with butter. Expensive.
Down
  1. 1. Technically a brine shrimp, but sold as a magical "instant pet" to children. Too small to eat.
  2. 2. These are often called "rolly-pollies" and their proper name is "isopods," but you can also call them this. Not commonly eaten, but sometimes, if they get big enough.
  3. 5. Tiny shrimps that penguins love to eat, as well as blue whales. A bit too small for us to eat.
  4. 6. A little guy whose body is built to hide in abandoned snail shells. Not for eating.
