Want to make Halloween drinks for a party, please help!

Okay so I had an idea but I’m not a bartender and have little experience with drink mixing, but my friends and I are making various drinks for a Halloween party and I wanted to ask how I could go about making them as I’ve been designated as the mixer (I have a smart serve but that’s it, no professional/formal experience)

So the first drink is themed after bride of chunky, it’s going to be in a champagne glass, and my friend was thinking of just doing a red dyed champagne with little gummy eyeballs thrown inside

The second is to be themed after house of 1000 corpses. It’s going to be in a wine glass, but I can’t personally think of anything super creative with wine lol

The third is themed after beetlejuice, and it’s going to be a mudslide in a Margherita glass topped with crumbled Oreos and crumbled green dyed cookies for moss, and gummy bugs around the rim

And the last is going to be shots themed after sleepyhollow, and I was thinking of doing a light blue shot like mostly rum with a tiny bit of blue curaçao, with some snowflake sprinkles, and then layered with something red for a blood effect.

I guess my question is what could be recommended or done for the wine glasses and how could I go about my idea for the shots?

Any ideas or even recipes really appreciated! I want to make some really cool drinks for my friends and make it a memorable night! 😄🖤🎃
