The 3rd Season of Sgt. Frog is one of my favorite seasons right now! I love the carp episode at the end of it! XD It cracks me up everytime I watch it! But in one episode, the narrator said that Kululu was holding Spaghetti >3< It was Curry! Now Kululu is saying clickie-poo and drinkie-poo more often...it's funny when he says those lines but now he says it too much in this Season...):
Ku! Ku! Ku! ([(@='@)])
I think there is a Season 4 because FUNimation spits the japanese Season order in 2 and release one every year. So now FUNimation has the Japanese season 2 right now, so they'd split the Japanese season 2 in half so they can make season 3 and 4 like they did with 1 and 2! So if they do release the 4th season next year, we'll have to wait for them to say if they licensed the Japanese 3rd Season to make 5th and 6th. I hope they will!
