Pigu kart... I'm there right now and I see it's well planned out. I support this suggestion and I have had a tour.

This is where you start! Jump on your pig and you'll be given a carrot-on-a-stick to guide it through this obstacle course when we're allowed out the fence gate, cleverly powered by redstone.

Once we're allowed out, we have to guide our pigs through the water in our way. Be careful!

This is a road which will have a pesky skeleton shooting through, so be careful and try to avoid getting hit, which is hard.

After, we get through a rocky road with bumps and more skeletons making your journey a misery.

Going through a thinner road with more skeletons, we will stop at a maze to guide our pig through out into the finish.

We find ourself at a hard maze to challenge ourself with! The first person who gets out will win the Pigu Kart.
