Our group was getting tired tonight when we hit Freehold, so we didn't experiment much with this. Here's what we think may work, but haven't tried.

There are several references to Sharkbait's favourite food being crackers, and there's a item looted off various pirate mobs in Tiragarde Sound and Vol'dun called Salty Dog Crackers with flavour text that reads "A favorite of salty dogs and parrots."

We suspect that it's as simple as killing the first boss, at which point Sharkbait briefly swoops down near the body and you offer him crackers, possibly by eating them near him.

I should be clear this is purely a theory, though if the item I mention isn't a part of it I would be surprised. We'll be going back in on Tuesday for Mythic 0's and will be trying this then. If any information has popped up before then, or if we try and succeed/fail, I'll update this post with correct information. If anyone has ideas or suggestion feel free to post them and we'll try various things. If anyone else goes in before next Tuesday and can confirm/deny this method, we'd appreciate it.

Final Edit: We have it figured out at last! The dish and the chow that we found earlier tonight are just 2/3 parts needed for the achieve, and credit to Philibuster for taking it home.

After the first boss dies, a dish will spawn next to the nest called 'Sharkbait's Meal Dish'. Have one player click on this and it will despawn. There will be no indication that it's been looted, no buff or debuff and nothing in your bags. Then proceed across the bridge towards the rest of the dungeon. As soon as you get off the bridge, go left a short distance to the spiral staircase that ascends to the top platform. Near the top of these stairs there will be a bag of food propped up against the railing called 'Gourmet Parrot Chow'. Have the same player who picked up the bowl collect the chow, and they will again receive no indication that it's been looted. Then proceed to the wooden dock directly north of the third boss' room and you'll find a blue bowl. If you've collected the dish and the chow, you'll be allowed to click to 'Serve Sharkbait's Meal' at which point he'll fly down and you get your achievement.

Here is a map showing the Dish (1), Chow (2) and Bowl (3).
Here is a screenshot taken by one of the players that found the third portion of the achievement, who sent it to me to help everyone visualize it.

Thanks to everyone (at least 4 or 5 groups that added me to btag to pitch suggestions or try things for me) for their contributions, glad we could figure it out! Now all we need to do is find Miimii, the Prince, and Solid Snake :(

My btag is FrostyShot#1667 if you have any questions about the metas. (US Servers)
