The 50/50 lifeline stays the same. The two different lifelines are "Poll the Herd" (Ask the Audience) and "Phone an Animal" (Phone a Friend). The viewer plays as Timon trying to help him be "King of the Jungle". Timon plays for grub, not cash. Meredith Vieira does make an appearance as host in this special feature.
