What’s the name of a game on Sagem?

Hello, I am looking for the name of a game that was originally on my old Sagem (which I don’t have with me anymore). I can’t find it on Google (as soon as you search for "game" you get a lot of download-to-mobile games... but not the list of games that were built-in). It's a game where the goal is to fill a large area on the screen (this area is blue, and white for the free space). In the white area there are little "creatures" moving around and you must not let them touch the line you temporarily draw... if you close the area bounded by that temporary line, the blue area grows. In the blue area there are also little "creatures" that must not touch you or you lose a life. And there is also a kind of "creature" that roams across the entire screen of the game... and you must not let it touch you either. Could someone tell me the name of this game? please Or would someone know of a flash version of this game on a site (flash or shockwave is fine, just to be able to play it on my PC)? Thanks in advance :)
