My internet went off for a little so naturally I played a bit of T-Rex Runner (Downasaur) to pass the time but got surprised with something I have never seen before when playing it, a cake.

It looked like a power up or a mushroom from Super Mario, it gave me a party hat and there were gray ballons flying in the background but unfortunately no extra life.

What's the reason for it to be added, I'm guessing it wasn't just a random improve of the game, is it to celebrate some birthday? Is there anything else I missed or is it just for visuals and does it matter if I jump over it and don't catch it?

Notably after getting the cake the hat stood through the rounds until I refreshed the page.
