I watched a little bit (or a lot) of Sprout every day when I was younger. I would watch all the shows they played at the time, including this. I still have a soft spot for Sprout and most of its shows, but not this one. It boggles my mind that I used to like this abomination.
I'm aware that a number of people find the character designs hideous, creepy, and unsettling, and I couldn't agree more. I've seen little to no creepier character designs in all my life. I heard somewhere that the character's faces are real life people's faces edited to look cartoony, which makes them as creepy as they are. I'm guessing their bodies are animated. Something about combining realistic and cartoony designs doesn't work. I've never seen any other cartoon quite like that before. Sprout quit playing Dirtgirl World because it scared a lot of kids. Amen! Grubby the worm looks like a rip-off of Grubby from Teddy Ruxpin, who is much better!
Dirtgirl doesn't know how to garden correctly. To make matters worse, she is briefly shown jumping on her bed during the theme song, which looks dangerous. I assume she has never heard the song "No More Monkeys Jumping on the Bed." The show encourages some inaccurate "facts" and bad lessons about gardening, plants, and those kinds of things, like "corn is overgrown grass" and "always stay dirty."
Whatever you do, don't watch Dirtgirl World. It will likely give you nightmares or scar you for life.
