Season 10 - The European trip
This is being shown in COZI TV now. I just can't imagine how parents can leave their kids for 6 months to wonder around Europe. That didn't make sense. Maybe I missed the episode where they explained why they decided to do that.
Also... when they returned it seemed like Charlie and Bunny's baby had disappeared from the show. They lived with Linda and Rusty while Danny and Cathy were in Europe. But there was very little (if any) mention of their baby. And when Danny and Cathy returned there was no sign of the baby at all.
That season was so confusing
