This is what happened. I had a song going around in my head for ages and couldn't remember the words to it, so I kept singing...Scooby dooby doo doo doo...etc. etc. You get the idea, so Scooby was named because of the song, then when I got Dooby.......it just sort of fitted in place. Darryl has a rabbit called Ruby, so now we have Ruby, Dooby and Boy!!! Oh yeah, and Tigger, Ziggy and Jazz, the guinea pigs. LOL.
