Another angle: "imskirby" maybe an internet meme or inside joke. If they saw a video titled "imskirby dog" at an expo, perhaps it's a humorous take where a dog pretends to be Kirby. Maybe a YouTuber made a video where their dog performs as Kirby in a parody.

Skirby... Oh, maybe "Skirby Dog" is a specific meme or character they're referring to. The user could be looking for information on a viral video involving a dog and Kirby, possibly from an event like an expo. But expos like E3, PAX, or others usually feature game reveals. Maybe it's related to a new game or a meme that appeared at an expo.

I should check if there's a known event where this was showcased. The user might have heard about a video at an expo but spelled the name inaccurately. Maybe they mean "Skyrim" crossed with Kirby, but that seems unlikely. Alternatively, "Skirby" could be a typo for "Kirby Skye" from "Star vs. the Forces of Evil," but that's a stretch.

I should start by confirming if "Skirby Dog" or "Skirby Dog Video Expo" is a real thing. If not, the response should address that and explore possibilities: a fan-made project, a meme, or a misunderstanding. Maybe the user is referring to a specific indie game or a viral video that hasn't been widely reported.
