Mushroom island portal

The mushroom biome is a very rare place to find, yet doesn’t seem to have a reason to go there! so I think that there should be a portal when you go there, It can be made out of mushroom blocks, and the portal entrance should be red with white curls just like the nether portal. But when you enter the portal you will be amazed you will see gigantic mushrooms of different colours, It can have new mobs like maybe a tiny mushroom mob that can run around a lot, and there obviously will be a lot of mushroom cows there!
