Surveillance video shows someone _ police think it was a man _ in a bulky, green costume and another man entering 7-Eleven in Rancho Penasquitos early Monday.
Gumby demanded money, but the store clerk thought it was a joke and ignored the life-size Claymation character, telling him he was cleaning up and didn't have time to waste, said San Diego police Detective Gary Hassen.
"You don't think this is a robbery? I have a gun," the costumed man said, fumbling inside his costume as if trying to retrieve a weapon, Hassen said.
But the green-gloves seemed to get in the way, and rather than pull a gun, he dropped 26 cents on the floor, Hassen said.
