Birthday Drink Idea Help

My best friend’s birthday party is tomorrow and I need help thinking of a good drink. I have never made anything fancier than mixer + alcohol, so I would love all the suggestions!

Criteria: make a themed cocktail themed about things she likes. There will be 8 of us competing & she said she will be judging based on taste, presentation, creativity, name of the drink, and the song you present your drink with.

My top ideas are focusing around the song, so the songs she likes: Under the Sea, Dirty Diana, or Fat Juicy and Wet (the last one would probs be the funniest).

She loves tequila & rum, she also likes a spicy drink but it does not have to be spicy.

Any ideas??

P.S. ingredients need to be normal enough that I can find them at a regular liquor/grocery store.
