Two-year-old Marshall Shaffer went to the Point Defiance Zoo in Tacoma, Wash. on Halloween dressed as a tiger cub. Thanks to that disguise, he made quick friends with Kali, a gorgeous 6-month-old Sumatran tiger cub that lives in the park's tiger exhibit.

In the video, the new pals play a game of tag. But don't worry: Marshall, giggling as he races back and forth, is blissfully safe thanks to the thick glass barrier between them.
