Surma didn’t solve the cube, so it isn’t highly intelligent... maybe, though it might just have not bothered with the cube (or couldn’t solve it due to massive claws) and it is instead watching our stick-y boi from the shadows while he’s distracted with his lil’ toy, which is still quite intelligent if you ask me.
Either that or it’s staring at Lalli, as Lalli is staring back at it, not bothering to hide, cuz’ it’s so damn CHONKY!
