Quicksand is the second episode of Ben 10 Ominihero.
After meeting Galord for the first time, the team is flying through space, where Ben receives a call from Eunice from the Omnitrix, where she reveals that they are in another dimension and Ben figures out that the Omnitrix has lost the access to all of his former aliens.
Underground, they are attacked by a group of guards, and Ben transforms into Sandbox for the first time. Because of this, a kid mistakes him for her father, as well as her mother. In order to avoid more confusion, Ben detransforms, and then is hit by one of the guards.
After he wakes up on the mother's house, he meets with the rest of the group, and it is revealed that her husband was captured by Galord. After a flashback, they are confronted by the Peltroan, and they fight both of his forms, first underground and then on the surface, where Ben turns into Big Nose. After he is defeated, Ben cures him, and it's revealed that the Peltroan was the Sandor who was captured by Galord, who comes from his ship and attacks them. Ben turns into Power-Up to fight him, but they are easily defeated. Because of him, the father is lost again, the mother's house is destroyed and many are killed, and so the mother bans Ben and his team from the planet.
On the ship, Professor Paradox appears, and tells Ben that this is the first timeline where him and the team have met Galord, and because of this, there is no way to know the possible futures of what will happen, because they haven't been realized in any way yet.
