Favorite Jem Memory

This will be my 4th Jemcon, attending in 2018, 2023, 2025, and 2026! Jemcon is the best fan convention because its fans are the BEST!

In 2025, I was so thrilled to have my Rama Llama immortalized life-sized, along with Glitter 'N Gold Jem and Rio, as the top costume winners!

I'm so honored to be invited back, I can't wait!
