Sunway Lagoon waterpark in Greater Kuala Lumpur, Malaysia, has launched a new offer in an effort to entice visitors during the week.

The new 'Quack-tastic Tuesday' offer grants entry to the park at a discounted rate of MYR40 ($12) per person.

Celebrating its 40th year of operation in 2014, Sunway Lagoon has a series of anniversary events planned throughout the year, including the MTV World Stage concert and the Nights of Freight Halloween Special.
