What scares Leeteuk almost to tears in the jungle?

Poor Leeteuk...

On the June 10 installment of SBS's 'Laws of the Jungle,' tough leader Leeteuk of Super Junior showed his weak side - weak yet adorable and endearing!

On this day, he was determined to climb a tree in order to get ahold of a coconut despite there being fire ants on the tree.  However, as he climbed up, there were just too many fire ants and he shuddered at the sight.

His peer, Jang Hee Jin, tried to soothe Leeteuk, who wanted to get down from the tree because of the ants, but Leeteuk looked as if he was about to burst into tears anytime soon.  He revealed that the only thing he was scared of was ants, screaming, "I said I wasn't going to come [to the jungle]!" causing laughter.
