Those are totally glow-in-the-dark swords you see. Along with pirate hats. I visited the dollar store.
Not pictured are the kids running around outside. Or the crafts they did. I had pirate coloring sheets, they stamped/drew pirate treasure maps, and colored messages to stick in bottles. The maps were made from paper grocery bag pieces/scraps, the message bottles were clear water bottles that I ripped the sticker off. Yeah, sometimes mama’s cheap. But it works. Add in the pirate hats and eye patches and glow in the dark swords for everyone, they had a great time. And this was my first themed birthday part since the boy was 2yo. That year, hardly anybody showed up so for the next several years I just did a birthday playdate or we did our own family thing
