Big Bounce Byway is the fourth level of World 4 in Super Mario 3D World.
The level is set in a grassy mountain area. The first portion of the course is filled with Mushroom Trampolines and enemies like Biddybuds and Spinies, as well as the Checkpoint Flag. Following it there is a giant elastic platform that moves slowly across the sky to the Warp Box that leads to the Goal Pole area, an isolated piece of land with a few Hop-Chops.
- Green Star 1: Near the first three hop-chops, find the one that turns into a spring and use that one to jump on the ledge where the star is.
- Green Star 2: Right after getting the first star, bring the spring with you past the checkpoint and under a pair of bouncy platforms. Just wait for the platforms to lower down so you can bouncy on them towards the star.
- Green Star 3: After bouncing off the bouncy platform to a ledge, go in the Mystery Box hidden in an alcove. In the box, find the right hop-chop that turns into a spring and use it to reach the ledge with the star on it within ten seconds.
In the last group of Para-Biddybuds, go to the middle of each circle to get the Mushroom Stamp.
