Jumping flea is a basic rocket containing most of the parts in the early career mode.
|“|| The Jumping Flea was originally named after the carnival ride that we salvaged most of its parts from. It might not get us all the way to space, but it will definitely get us started there with a bang!
- Despite being called a jumping Flea, it never jumps again after jumping for the first time.
- It's impossible to steer.
