It's a joke ! Very nice simulation !
Not a glitch doughnut, it is just like that for certain things.
wow i havent seen one of these in a couple years.
Im not sure if this is a glitch but when I copied the circle deleted the one in the box then pasted it unpaused then kept pasting it everytime I did it the game would pause which is doesnt with anything else pasted devs might need to check that out...
cats15: I discoverd something like this a year ago (except with bubbles, not worms), and I even made a save which showed hoe to do it, but so badly. Here, finally someone could explain it better than me. From me, it's a +1.
Also, the worm can cure viruses =D
I poured some lava and the worm avoids them!
