Plastic sheep

I had an idea for a mob called the “pleep” that would be similar to a sheep like how there is cows and mooshrooms. You can craft a pleep with 1 wool, 2 iron ingots, and 6 copper. It could be dyed like normal sheep. Instead of eating grass, it would eat mycelium. It would drop 5-15 plastic shards of the pleeps color when sheered. Plastic shards could used to craft plastic blocks or plastic tools. Plastic blocks would be used for mostly decoration and it would break very fast and have low blast resistance. Plastic tools would be like wooden tools but they have less durability and they can be different colors depending on the plastic shards color. The plastic shovel when used on sand creates a sand castle. You can use a water bucket to add a moat around the sand castle
