Biodegradable cruise ducks would be a cool idea if someone can invent that please.

Cruise ducks are fun and all, but what would be cooler is if you planted them in the ground they grew into a tree or flower or something. Something to help the planet, not add to landfills. Glass ducks are probably recyclable. Are the glass ducks you sometimes see made out of actual glass, or are they a hard plastic? I'd rather have a biodegradable soft, colorful duck than a small, monochrome hard duck that can break and possibly injure people especially in the pool area. Cruise ducks would cost more if they were made out of biodegradable material. You can find find biodegradable plastic bags at your local grocery store and they are great for composting. I'd gladly pay more for biodegradable cruise ducks if someone decided to make them. You could make a killing. I think.
