I think it's a sign of the rapid maturation of the kids music video genre that this video for "My Magic Trick" from the Ralph's World album All Around Ralph's World is nothing special. Don't get me wrong -- I like it and think it captures Ralph and the song very well. But it would've stood out production-wise a couple years ago and it doesn't now.
(Am I the only one who kept expecting a big giant foot to squash Ralph at the end?)

Video: "Obsessed by Trucks" - Justin Roberts
That's funny -- the singer looks nothing like I expected Justin Roberts to look like. (j/k -- it does feature a brief, blink-five-times-and-you'll-miss-'em appearance from the Justin and the Not Ready for Naptime Players.)

Video: "When One Became Two" - The Verve Pipe
The animation for "When One Became Two," the first video from The Verve Pipe's great kids album A Family Album is by Ofir Sasson and reminds me of Shel Silverstein with some Dr. Seuss mixed in, very fanciful. It's a little rough in its animation style, which fits the organic and relaxed vibe of the song. They fit together very well.
