Buffy the Vampire Slayer: Here's how to celebrate its 20th anniversary

Buffy the Vampire Slayer turned 20 a few months ago — but that doesn't mean the celebrations have to end there.

This year's San Diego Comic-Con will feature a fan event on July 22 that will allow all members of the Scooby Gang to not only participate in a range of Buffy-themed activities but also purchase new merchandise tied to Joss Whedon's series.

The night's events include both a Buffy Fandom Feud Trivia Contest and a Buffy Cosplay Contest, with fans testing their knowledge and cosplay abilities to win Slayer swag. Attendees will also be able to have some Buffy 20th anniversary cake and signature Slayer-inspired drinks while displaying their improv (and memory) skills as they try and recreate scenes from the show's beloved musical episode, "Once More, With Feeling!"

Other episode-specific opportunities include a chance to take pictures with a life-size image of iconic "Hush" villains The Gentlemen. And while there will be giveaways happening throughout the event, social media-savvy fans of the show will get a chance to win an exclusive spell from the previously announced Buffy the Vampire Slayer: The Official Grimoire (available later this year) stored in a small glass vial.

There will also be stations where fans can test out the Buffy table-top board game and interactive wall-sized Buffy coloring pages.

Those interested in attending can register on the official Buffy Facebook page, where portions of the event will be live-streamed.

Among the items up for sale (all of which will be released later this year) are:
