The title here and the banner that Giroro's holding is just making fun from the famous Japanese movie "The Seven Samurais"...I didn't invented the joke though! The screenshots from the referenced episode could prove that: [link]
And for the characters themselves, they are parodied from "Seven of Seven", another anime that Mine Yoshizaki has took part in. _{Thanks for ~Ringo-chan101 for the info!}

After testing the "drag and drop" function here([link]), now I could make a more serious dress-up game. Since the Sgt.Frog series have many dress-up/cosplay scenes, seems like it would be really fun to make dress-up games based on the characters(and the Kerons are easy to draw too!).

I added sounds to the game this time to make it more interactive--you have to hold down the mouse to see the translation though, for I don't know how to fix the dialogues there...

[Edit: I checked the Etiquette Policy of dA and found that I shouldn't use sound clips for a Flash file, cause that will be violating the policy... Therefore I changed the file into voiceless version. You could still listen to their voices here, though: [link] ]
