Please correct me if I am wrong.
Now that you mention it, I can see the resemblance. If you saw it in person the thought wouldn't cross your mind tho as it is about the same size as most other Hot Wheels.back to the orig. question...
don't know about the others... but that yellow bird car looks veeerry interesting...
looks to me like a Zowie, from back in the 70's... did McD's have a Happy meal toy that was a Zowie?
