This is my niece, Kashmala, playing on the computer when she was a month away from turning 3. Basically, what's going on is: "Gadulation" in Kashmala's (back then a little under 3 years old) language meant balloons, celebration, congratulations. We had just returned from a graduation ceremony and had taken balloons for the friend who was graduating, so Kashamala understood balloons = congratulations = graduation :) Isn't she adorable! God preserve her! In this video, she's playing a game on the computer, and it looks like a balloon pops up and that's why she says, "Gadulation!"
