Big Bounce Byway

Big Bounce Byway, also named World 4-4, is the fourth level in World 4 of Super Mario 3D World. The player gets access to it beating Brolder Blockade, and its own completion unlocks Spike's Lost City. The level's setting are grassy mountains.

Layout
The first portion of the course is filled with bouncy platforms 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 Stars

 * Green Star 1: In plain sight inside a hole in the wall near Hop-Chops at the start of the level. The player can use a Hop-Chop as a Springboard to get there, or alternatively climb the wall with a Cat suit.
 * Green Star 2: After the stairs near the Checkpoint Flag, players can use a Springboard or the Cat power to reach two bouncy platforms with a Green Star above them.
 * Green Star 3: The character must enter the Mystery Box near the big bouncing platform. Inside it, they can use a Hop-Chop or the Cat transformation to climb a fence and get the Green Star.

Stamp
The stamp is in the middle of two wheels of Para-Biddybuds during the big bouncing platform ride.
