Four of the contestants are thrown headfirst into the challenge, and start the episode sky-diving out of a helicopter.
"I'm really, really, really, really, really nervous," said Alfonso Ribeiro, best known as Carlton on The Fresh Prince of Bel-Air, before making the jump.
"That was sick," said TOWIE star Joey as he landed.
When it came to facing the first creepy-crawly challenge though, the "Rotten Roulette", the blue-eyed hunk appeared less confident.
"It's scratching the hell out of me," squealed Joey, as a lizard crept towards his manhood. "He's biting me."
Which star wiped tears from his eyes as he emerged from the glass coffin full of scorpions? Which contestant said they were ready to "break the rules"? And which team will end up spending a night on Stradbroke Island, the mecca for venomous snakes?
I'm A Celebrity... Get Me Out Of Here! starts on ITV1 on Sunday night at 9pm.
