Same thing happened to me almost 2 years ago (minus the parrot). Had been delaying swelling battery change because I needed MBP every single day for work. Brought it in to get it checked after the spill, expecting to be told the inside was done and I would need to get a new machine. Liquid check passed, decided to change the battery. Turns out battery replacement comes with top case replacement, including keyboard & trackpad. Best 250$ spent ever. MBP 2014 looks like new and still going strong to this day 
EDIT: Meant to reply to ERJ_T… oh well… But in fact, I have a story about « lost device » too. Same MBP, left in my open bag with wallet, passport etc in a passenger seat on a train in Italy, from which I got off in a hurry to catch the next train. Realized what I had done on the next train 
Still cannot believe I got everything back, including all the money in my wallet!
