Plot hole: The alien mummy is found by the werewolf in a separate rectangular block of concrete. However, I don't think that the Tennysons would have made the effort of first enclosing the mummy in a separate load of concrete, waiting until the stuff is hard, then putting it into the hole and covering it with a new load of concrete. Too much effort and too little time for one night ("Under Wraps"), since concrete does take time to get hard properly.

The Big Tick - S2-E2
Trivia: 2-2 The Big Tick: When Ben tries to find out what his new Cannonbolt form can do, he makes some hand movements. These are in effect the same as made by Tobey McGuire in the first Spider-Man movie, where he first tries to shoot his webbing purposely.
