Can anyone help me I'm going crazy!!

I need to know what the name of the show was on kids TV (could be bbc or ITV) in the early 90s.
It featured an alien who had ears that were back to front and because of this he had to wear a hat that covered his ears all the time. The other main character was a young boy who befriended the alien.
Any input greatly appreciated.



PS Im new here... Hello all.
