The Lava Lamp Gun can be used to destroy obstacles, as Kevin shoots some lava at the safe the crown is kept in, and when he does this, the door melts and allows the Minions to see the crown.
The Blind Tower Guard prevents them from stealing the crown, so Kevin attempts to shoot lava at the guard, but the guard plugs the gun with his walking stick. Soon the lava gun explodes and the Tower Guard is trapped in a medieval helmet.
As Kevin, along with other Minions, follow the crown as it is being taken away from the tower, the gun is seemingly left inside.
