Two very different franchises just collided. The latest trailer for The Angry Birds Movie 3 features a surprise cameo from Sonic the Hedgehog, who appears doing what he does best — running — alongside the speedy yellow bird Chuck.

The appearance is brief. GamesRadar+ describes it as a blink-and-you'll-miss-it moment, and the reaction online has been less excitement than confusion, with fans openly puzzling over why SEGA's mascot is turning up in a Rovio film.

There's some corporate logic lurking underneath: SEGA acquired Angry Birds maker Rovio, putting both the hedgehog and the birds under the same ownership umbrella. That makes the crossover less random than it looks on screen — even if the trailer offers no explanation for Sonic's presence.

Whether the cameo amounts to a single sight gag or something more substantial in the finished film remains unclear from the footage. Either way, it's a crossover nobody had on their 2026 bingo card.
