Mechanicat could be purchased for $14.99 in the limited time "Best Deal!" which included 25000 coins, 1800 DNA, a Triple XP Boost and a Double Mass Boost. This skin was not available for individual purchase and may not be available for purchase in the future.
Details of this skin may vary depending on location, platform or time.
Note: The third part of the Mad Gears Shop offer was released again for limited times in mid January 2020 and then in early March 2021. The price and included items for Mechanicat remained the same for both of these releases.
