Kali the tiger cub is clearly eager for a play date.

In a video from Halloween that's making the rounds on YouTube this week, a 2-year-old boy dressed in a snuggly tiger costume toddled up to Kali's enclosure at the Point Defiance Zoo & Aquarium in Tacoma, Wash.

The 6-month-old cub was so enraptured by the little tiger-boy that she mirrored his every move through the glass and even tried reaching out to him several times.

The encounter was so exciting to the boy, Marshall Shaffer, that he giggled and squealed nonstop.

"I think you tired her out, Marshall!" dad and videographer Heath Shaffer finally said at one point after Kali collapsed for a moment, panting, but keeping her eyes fixed on her bewitching new friend.
