Above: Smash Stadium. This was the first concept to be developed for the show. It's probably the most important environment in the whole show. This is where the Gridsmash games take place - a giant floating stadium in space, complete with giant navigational rockets and spinning gyroscope. Add in a little Speed Racer Movie crazy light show and holographic adds and you've got it. The little dots on top are the bleacher pods that fly in from various planets.
Below: I submitted 3 ideas for the Smash Stadium with an emphasis on rockets, light shows, massiveness, holographic advertisements.
Fold out teletrons!
The Announcer Droid was designed as a pseudo narrator to explain the game to the viewers. It was thought of as part of the stadium, so it was determined to be a mechanical robot from the start as opposed to a biological or humanoid character.
We tweaked the designs and removed the rockets in favor of a little variety and wackiness. I kind of thought of it as a big shell with all sorts of hidden mechanical appendages that could come out of portals and hatches. Navigational paddles allowed for flight and gesticulating.
At one end of the grid field, Grizz would observe Johnicco's progress from his secret room at the top of a huge observation tower. The tower base didn't change much, but we went through several iterations for the top as we fiddled with the scale of the field and as the actual physical interior the puppet team created was being developed.
