Joe made some pretty sexy teleporters which make traveling from Spawn to the Mushroom Biome quick and easy. Using the teleporters requires a level of 5 or higher, and costs 1 level.
First, you step into one of these nifty pseudo-TARDIS looking teleporters, which will send you up to the teleportation hub.
High above spawn is the hub for the teleporters.
Very high above spawn.
Inside, you can waltz over to the teleporter of your chosen destination, hop inside, and press the button to be off. Or, you can buy emergency teleporters which can be thrown down on the ground anywhere in the world and will spawn a teleporter to bring you back here.
OMG I AM LOST, good thing I have my handy-dandy ETP crystals with me!
You can't bring your horse with you, though. It doesn't fit.
Enjoy and happy travels!
