Under Wraps

Under Wraps is the thirty-fourth episode of Ben 10.

Plot
In order to teach Ben and Gwen the value of hard work, Grandpa Max takes them to a farm. Ben and Gwen at first struggle with farm life, until Ben convinces Gwen to let him use the Omnitrix to complete their work faster and easier using four of his aliens.

However, a farmhand tells Ben and Gwen of a Mummy that had recently arrived in a flash of purple lightning, like the Yenaldooshi did, prompting their curiosity. The two of them sneak out during the night and find it digging for a strange stone.

But the Mummy attacks them as soon as it sees it. XLR8 fights it to no avail, but the mummy flees in the confusion. Max discovers that the strange rock is an unstable element called Corrodium, which causes severe mutation in Earth born species demonstrated by cows on the farm.

Max states that Corrodium does not occur naturally on Earth thus speculating that it crashed to earth 65 million years ago, when dinosaurs died out. The Tennysons track the mummy down to a ice cream factory, built on a Corrodium meteor. Ben uses Diamondhead to dig up the meteor, but Gwen points out that he just did the Mummy's work for him.

Worst yet the mummy proves to be invulnerable, rapidly healing from any and mutates a security guard with the Corrodium.Gwen and Max deal with the guard while Diamondhead fights the Mummy, only to revert to Ben mid-battle. In the resulting struggle, the mummy touches the Omnitrix and it goes into Scan Mode and unlocks Benmummy.

When Ben tries to transform into Benmummy the Onnitrix transforms Ben into Upgrade instead. Upgrade merges with a liquid nitrogen containment tank and sprays the mummy with it, freezing it solid, Max buries it in concrete in the hole Diamondhead dug. Then flee the town in fear of more manual labour at the farm since Ben and Gwen have learnt their lesson.
