Dumai, a Sumatran tiger, and Berani, a Malayan tiger, can’t get enough of the water spraying into their enclosure at the Point Defiance Zoo.

The two hand-reared cubs are about a year old. But they were paired when they were just a few weeks old, and they act like brothers. While Dumai was born at the zoo in Tacoma, Wash., his pal was transferred there from the Tulsa Zoo to keep him company.

Watch their antics below, and then go back in time to see when these cuties first met.
