Super weird! And I would expect the left one to be “gull skate,” but its blanks are [6] [3]. I also don’t remember this one being in the purple room yesterday, so I’m wondering if some things moved around or something?

I changed this puzzle after release (the original was too hard/unfun). I think you're on the old version of the program (which is why the letter counts don't match) but your browser loaded the new art.
Try reloading the page and hitting Continue from the main menu. Or you can enter the solutions for the original puzzle which were SPINAL FIN / FINAL SPIN.
