Recently our little boy has been crazy about whales and sharks. (Especially sharks!)
He's always talking about sharks, looking at pictures of them, and watching them (or asking to watch them) on television. He sleeps with a plastic shark and a whale, and he probably says the word "shark" over 100 times every day. It is really cute!
We've found two cartoons that feature sharks. One is "Misterjaw", which is played during "The Pink Panther Show" on the Boomerang network. The other is a newer one called "Kenny the Shark" on Discovery Kids Channel. He really likes both of those cartoons. We have them on our DVR, so he can watch them as often as we let him.
The cool thing about "Kenny the Shark" is that there are some of our little boy's favorite words repeated frequently during the show. One being "Kenny" (my son's name), and the other being "shark".
We'll keep riding the sealife-boom until the next thing comes along.
