4. The Sundae Slide
The deceptively treacherous Sundae Slide sometimes served as the omega obstacle. In such cases, contestants who managed to ascend its pudding-slicked incline saw promises of a Brand New Car, free enrollment at US Space Camp, or an equivalent bounty waiting at the depths of its spiral. But those who thought themselves home free after they made it up the ramp invited overconfidence to bring about their downfalls. The real tricky part about the Sundae Slide was finding swift sure-footedness in a kiddie pool full of whipped cream.
3. In One Ear
In another universe, it could've been a plot of a horror film: The host, chuckling at this ghastly display, forces children to squeeze through the tiniest orifice of a human skull. His victims muddle past rotting brain matter and gobs of festering ear wax, then emerge, physically and emotionally tainted, out the opposite side. For these efforts, which have cost them their sanity and immortal souls, the host awards them a Lonestar Singalodeon.
