The Secret Weapon / Camp Invisible / a Christmas Tale / the Bull of The Ball

Camp Swampy receives a new secret weapon, but it looks a lot like the new organ intended for the post choir. While cleaning up for the big inspection, Zero grabs the wrong can of paint, special "invisible paint". As he works, Camp Swampy disappears. It's Christmas Eve, and Sgt. Snorkel dreams of "The Night Before Christmas"...with Gen. Halftrack and Pvt. Bailey as the stars. Beetle enlists Cosmo's aid to win Bunny back from the local playboy.
