Maybe something like this would be cool a Ping Pong Machine Tardis the door would be in the middle part and when u open it the sound would be a Ping Pong machine win sound i think that might be cool and the recipe main item for the chameleon would be maybe like a concrete block or something hopefully u guys like it il make other ideas later this one was just a fast thought and this would be atleast 2 blocks wide

Maybe its could be a server for the recipe
