I found a green tree snake in my house today and it had a few battle scars on it, but it also had three or four lumps under its skin like 'worms' about 1 to 2 cm long. Stupidly, I didn't take a photo before I let it go. Any ideas on what they could be? The other interesting thing is we found the snake because of the noise it was making as it slithered across our tiled floor. It was such a loud hissing noise like a split in a hose.
