There’s an official reference sheet that shows Pearl can make her spears sword sized… It’s called Wand Form.
Whether it’s a hint that she’ll do it in the upcoming episodes, I dunno.
But officially, she could do it.
Oh! Thanks for the info and the ref! I wasn’t aware of those. I’m pretty sure now that this particular image was just an editing problem though, when they cut and resized the logo for twitter.
There was a problem with the previous storefront so if you wished to order the zine but couldn’t previously, you can do so now on this updated storefront!
