The park is expected to be operational by the first quarter of 2019 on a budget of Rs. 450 crore. It will spread across an area of 61,000 sq m and will have family entertainment destination with 33 theme-based attractions as well as 20 unique water-slides. It will be divided into four major sections – a theme park branded by Cartoon Network, a water park, a family recreational hub and a service apartment and retail shopping area.
