But why would he want to free Swirly D? If Plungers are tools of war, that means that swirling people is easier (because the toilet wouldn't be clogged); so, I can see why you would think the Sgt. would be connected to Swirly D-- but why would such a man as he be wanting to free Swirly D? I feel like he must of been either lied to by a commander higher than him, or nobody had any knowledge of a Swirly D and just wanted the toilet to be unclogged for their own use.
If it is the first one with an upper commander lying to him, what a sad story, I hope it is expanded on and you can defeat the upper Sgt.(s)
If it is the second one. how? If you are invading or warring you would think you would know what the other side had, unless Swirly D is super ancient and people forgot about him (unless it's some sort of magic the "Master" put on Swirly D so people forgot about him so they wouldn't try to get him out? It maybe could happen like that, so when he got out the magic was broken and people remembered him again, unless it was just Swirly D swirling everyone into remembering him)
