However, my search did lead me to something really fun. A popular bento trick is to slice a hotdog like this so that when it's boiled the legs curl like an octopus. That's adorable and an easy trick that can prevent a full scale MUTINY when you run out of hotdog buns! Another cute thing I've seen online is poking uncooked spaghetti through chunks of hotdog, then boiling it and you end up with spidery looking things like this. My kids like to call them squidlets. [If you are hotdog-averse, Lindsey at Filth Wizardry also tried it with ham and carrots.]
So, we tried to make a few other things. Aliens, robots, beta fish, a trophy cup, and even an elephant.
Not all of them held together perfectly when boiled. Our trophy cup lost a handle and the fish lost a fin... but the point is that your imagination can help you move beyond the sea. Let me know if you've created any other fun things with pasta and hotdogs!
Remember that small slices in the hotdog with a sharp knife can create awesome muppet style mouths which open up when boiled. You can even try letting the kids poke holes in the hot dog with a fork. Grab some (organic, nitrate free) dogs, some (organic, whole wheat) dry pasta and make something funny for lunch.
