Ep 4. Merry Christmas

In the Ben 10 season 3 episode titled "Merry Christmas," Ben and his family are gearing up for the holiday in Bellwood. As they begin the preparations, things take a surprising turn when Ben's Grandpa Max reveals his plans for a special Christmas gift - a trip to Aspen for the entire family!

Ben, Gwen and their cousin, Max Tennyson, are all excited about the trip, but Ben is still concerned about the Omnitrix. He knows that the villains in his life won't take a break for the holidays and he feels a duty to protect the world as he always does.

Once the family arrives in Aspen, they find themselves caught up in typical holiday madness - skiing, snowboarding and ice skating, among other activities. But things take an unexpected turn when they stumble upon a sinister Christmas secret.

As always, Ben is quick to spring into action, transforming into various alien forms to take on the villains. Along the way, he enlists the help of his trusty sidekick, Kevin Levin, who is more than happy to lend his strength.

Despite the chaos and danger, the family manages to enjoy the holiday season in their own unique way. They celebrate with a Christmas feast, with all their favorite holiday treats. And Ben even gets a chance to hang out with Santa Claus himself!

In the end, the family learns the true meaning of Christmas, and that even in the face of danger, love and family can conquer all. And as always, Ben proves that he is a true hero, willing to fight for what's right, even on a snowy Christmas morning.
