Once Upon a Time fans were hoping the show's writers would use Comic-Con to reveal new details about Season 3, and they did not disappoint. After spilling a number of vague — but exciting! —  spoilers, the show's panel ended with a splash. Literally!

This teaser promo closed out the panel, and we couldn't have asked for anything more. The video clip shows Grumpy having himself a nice little picnic by the docks. Unfortunately, his meal is interrupted when someone makes off with his fork. Yes, his fork.

Who would steal a fork? you wonder. Why, a certain red-headed mermaid with a love of trinkets from the world above the sea...

That's right — it looks like The Little Mermaid's Ariel is definitely coming to Once Upon a Time Season 3, and we can't wait! Although we don't yet know who will play her or what part she'll have in the story, we're just excited by the prospect of meeting a mermaid.

Check out the teaser promo here.

Catch the Once Upon a Time Season 3 premiere on September 29, 2013 at 8 p.m. ET/PT on ABC.
