Anyone know where to find Goofy christmas lights?

My sister in law swears that she saw some Goofy christmas lights a few years ago. She's a huge Goofy fan and she refuses to put up her Goofy ornament tree until she finds them. No I'm not kidding. I would love to find her some and I have her name this year. I think she said that they are goofy shaped and there are no other characters with him. We have looked at all the obvious places.
