Lux's name randomly replaced with "Squill" in chat

So I was in a normal draft game and noticed that, when Lux went on a rampage, the announcement had her name replaced with "Squill". As you can see in chat, we thought it was the name of her transformation in the elementalist skin, but a few seconds later it was back to normal when she went unstoppable. Maybe it's a weird teaser like the random mark before Kindred's release, or just spaghetti code. Either way we found it kinda creepy, so I thought I should put it up here. Thoughts?

Edit: Turns out it's the name of Lulu's polymorph pet, no teaser today [zombie-nunu-bummed]
