While feeding the scaly children last night, a pellet somehow got stuck on top of Octo's thermometer. Octo kept hanging out near it and trying to hop up to get the food. After taking a few pictures, I finally took pity and got it out for him.
His tail is also very slowly growing back! Shh - don't tell him! The pictures aren't the best - sorry!
If you squint, you can see the pellet on top of his thermometer.
