My grandson has a bunch of Nerf guns. They shoot a small tube, like a tiny pool noodle, that one end is sealed with a plastic. We have Nerf shootouts on the porch. Sometimes a few don't make it into the toy box, when we pick up. Yesterday the duckling kept finding the ones we has missed. They're too big for him to eat, but I would take them away from him.
Today, he found one I had missed, picked it up in his mouth, and took off running. He KNEW he was not suppose to have it, and I was going to take it away. He ran to, and fro, darting all over, trying to avoid me taking it away from him. I walked swiftly behind him. He was so proud of himself, avoiding me so he could keep it. This lasted a pretty good while. It's too big for him to swallow, and as long as he doesn't sit down, and start picking pieces out of it, it's pretty safe. When he got tired, and sat down, I grabbed it from him. I replaced it with pieces of his duck food. Later on, I had my grandson toss one down. Quacker Sparkles came running, and grabbed it before it hit the ground. The chase was on. It's so funny to watch.
