The ModCheck meme, also known as the SpongeBob Fish Turns Around, features a green fish character from SpongeBob SquarePants looking frantically from side to side. While the character is a background extra in the show, the footage gained massive popularity as a Twitch emote and GIF. It is primarily used in live-streaming communities to signal that moderators are absent during chaotic moments in chat, or more broadly, to represent someone looking for something that should be there but isn't. Its expressive animation makes it a go-to template for expressing confusion, abandonment, or the search for a missing person or object in a humorous way.
