Yes, that is grass he’s eating.

Side note: we had a small earthquake here in Bali last night – a 5.2 originating in Lombok. I was standing outside in the kitchen but managed to not even notice it and even had to ask Made why everyone was running outside and shouting (Made’s dad was shouting the Balinese word for earthquake – linuh and I only knew the Indonesian – gempa). I thought they’d seen a big snake or something!
