Does anyone know where I can get a hat and an old jalopy for my crotchety old goby?

After almost 4 years of being an exemplary community tank resident my bumblebee goby has decided that he can't take the young whipper-snapper glowlight tetras anymore and he's started fin-nipping (I caught him at it). I'm setting him up a retirement village in one of my 5 gallon emergency tanks but does anyone know where I can find a hat and an old jalopy for my crotchety senior fish?
