Skytubes

History
In the early 90s Discovery Zone and Chuck E. Cheese was starting to become competitors in the Children's Entertainment Market. With this ever growing conflict CEC started to install more tubes and slides into the ball pits. This also lead to the redesign Chuck E. Cheese, giving him a sports outfit and later updating his look to be more mouse-like.

This competition between CEC and DZ lead to a major expansion of the tubes with the Phase 1 (1994) games package and given the name of "Sky Crawl". Then after the initial tests in Phase 1, the Sky Crawl was given a new name, The "Skytubes". The Skytubes were starting to being downgraded every update or remodel, they were originally able to take up an entire game room but after 2005 they only took up a corner. Eventually they were being phased out in the 2010s then completely being phased out in 2020 due to the Coronavirus.

Design and Features
Originally, the Sky Crawl had a marquee that read "Chuck E. Cheese's" in front of the tubes, a ball pit area for toddlers, and "The Chucksters' Lean Mean Cleaning Machine". There were also tubes with gradients and spots with small vehicles people can go in. Select locations had up to three layers of tubes, sometimes with more than one slide. Some went as far as to let skytubes go over or into certain areas where skytubes usually wouldn't be, like the kid check area or the showroom.

there was a rope under the tubes that when hung onto, you would swing to the other side of that area.
