You probably installed from Git, or directly from the source code using some other method. This is expected. Try installing some skins from mediawiki.org's skin directory, by:
Downloading the tarball installer, which comes with several skins and extensions. You can copy and paste the skins/ directory from it.
Downloading individual skin tarballs from mediawiki.org.
Aside from the previously mentioned Bot Shots as inspiration, Rescue Bots featured a very brief subline called Flip Changers that were larger figures motorized to roll after pulling a handle and then auto-transform into robot mode. Only two figures were made (Chase and Heatwave) and they were around $20 a pop retail. Wisely, Hasbro kept the design, ditched the motor and scaled the figures down to allow a better price point and selection as Flip Racers.
Selections started in packs of three before later releasing the Racers as individuals. Launchers and larger playsets were also available, often featuring unique redecos of earlier figures.
