The beauties took part in a zoology challenge, in which they put their hand into five crates with an animal inside, feeling it, and then naming each animal. The beauties were then offered immunity in a challenge where a disk was placed in a crate with 50 000 cockroaches inside, and the beauties had to pick up the disk with their mouth. The geeks took part in a "What's Your Number?" challenge, which had them approaching a female (a male for Helen) and asking for their number by flirting and finding interests.
