First appearing in A Day at Mato Land, Mato Land theme park designed by Professor Mato as a source of supplementary income. Funding for construction was provided by money stolen from Dawn that she stole.
The park is wildly popular featuring attractions that appeal to all groups of all ages, even the perverted (i.e., Jake). There are even robots in attractions, such as the stage robot Mr. Roboto.
Mato had designed a number of hypnotic traps into the attractions for research purposes, but safety commissions made him shut said traps down. These traps were reactivated by a shadowy organization hoping to obtain slave labor. These traps were able to ensnare the seven girls that accompanied Jake to the park before he found out what was going on and was able to put things right.
