In Wobbly Life, there’s a secret vehicle called the Rocket Bike, also known as the Rocket Car Ship. It’s one of the fastest vehicles in the game, and getting it requires a few steps. In this guide, we’ll show you exactly how to help the astronaut finish building it, collect the required parts, and unlock the bike.
How to Unlock Rocket Bike in Wobbly Life

Head over to the tiny island near the central space station. You’ll see an astronaut standing next to a nearly completed ship. Talk to him and he’ll explain that he’s building the fastest ship ever, but he needs your help to finish it.
Get the Nose Piece Built
The astronaut gives you blueprints and asks you to take them to the fabricator in the space mall’s cargo bay. When you get there, hand over the plans. The worker will tell you that you’ll need four pieces of Arrow Steel to make the part.
- Collect all four pieces around the area.
- Hand them back to the worker.
- He’ll process the materials and give you the nose piece.
Take this part back to the astronaut. He’ll attach it to the ship.
Collect Some Grease
The astronaut wants grease. According to his experiments, covering the ship in grease somehow makes it faster. To find some, head over to the Space Diner. Talk to the robot chef, and he’ll tell you he just threw out the old grease. You’ll have to go around the back of the diner and dig through the garbage. There, you’ll find a grease pool. Nearby is a bucket. Dunk the bucket in the pool to collect the grease.
Bring the grease back to the astronaut. He’ll apply it to the ship while finishing up the last few details and make the Rocket Car Ship.
