The Columbus Zoo and Aquarium posted a video of a toddler named Isaiah playing “peekaboo” with its two-year-old gorilla Kamoli last week.

The clip, filmed by Isaiah’s mother Sherry Chute, shows the youngster shrieking and laughing hysterically as the two chase each other on opposite sides of the glass enclosure — in what looks like a great workout for both parties involved. When it was time to go, Isaiah simply said “bye gorilla,” Chute told The Columbus Dispatch.

The footage has been shared nearly 6,000 times on Facebook.
