Ours was a big blue invader too! On a really windy day an empty blue trash can had blown onto the street in front of our house. THe wind was making it roll back and forth and for TWO hours Brinks refused to leave the window. He would watch it for a while and then growl at it. It was funny at first but got annoying after a while. I finally had to go outside and pick it up so he would calm down. Good thing I never have to worry about being picked on by a blue trash can, Brinks will protect me-
