Their last names must be Jack. I loved how adorable this was! It reminded me of "The Amazing World Of Gumball". Well, those kids were actually older. I loved the gags at the end. They really did behave like real kids!
That's not easy given how goofy this set up is. Even with a wacky world, you have to make the characters realistic. The voices are what really won me over. The designs of these guys was also very cute and creative. It's just a wonderfully feel good cartoon. It completely deserves its ridiculously high score.
