This was clearly not his day.

Gareth screamed when he fell through the floor and his fall was suddenly halted and then continued. He dropped on the floor on something that cracked beneath him. His torch had fallen beside him. He jumped up. He was in pain, bruised, but nothing seemed broken. Expect.... He glanced at what he had fallen on, stumbled back, and gave a shriek, that was cut off when he bent over and vomited.

Too bad he didn't vomit over the torch that was now lighting a hammock on fire.
