The 25th season of The Amazing Race has already seen nasty fights between teams and even seen once unstoppable teams fall to the back of the pack, but now a fear of heights could paralyze several of the teams as they continue racing through Morocco.

In a preview clip for the episode, titled I Feel Like I Just Kissed A Goat, teams will need to get through a major obstacle-as they are forced to walk and zip-line over a huge canyon in the Moroccan desert. Unfortunately for several of the teams, it appears that a fear of heights will get the best of them.

"I'm on The Amazing Race. I'm on The Amazing Race," Tee Jay chants to himself in the clip as he tries walking over the canyon.

Teams Have An 'Intense' Confrontation In Morocco

"It's pretty wobbly," Maya notes as she tries completing the task.

"I don't like it. I want to cry," Brooke says.

"I don't like being up real high," Misti admits.

In addition to dealing with their fear of heights however, teams will also need to once again deal with perhaps one of the biggest challenges in the race-dealing with wild animals-for the third time thus far. After dealing with wild Shetland Ponies and herds of sheep while in Wales and Scotland, they will once again be presented with the challenge of animals they're forced to try and control, as they try to complete a challenge of milking goats.

And sadly, for some of the teams, the experience may wind up being traumatic.

"If I see another goat I might puke," Tim says.

The Amazing Race airs Fridays at 8 p.m. on CBS.
