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! 😄🖤🎃
