(as seen in The Muldermas Guide, only this one has Xmas-y decorations!)

(1) Purchase an undecorated tramp-shaped pinãta form
(if these aren't readily available in your area you can:
(a)(i) tie together four long balloons and one round one to approximate the tramp-shaped piñata form as seen in Diagram 1.
(ii) Cover this with several layers of papier mache (strips of newspaper and white glue or flour-and-water paste work well)
(iii) allow to dry for 24 to 48 hours, or until the papier has formed a solid crust around the balloons.
(iv) Using a long, thin needle to penetrate the papier mache, pop each balloon.
Or
(b) move to a more interesting neighbourhood.

(2) Drill a hole approx. 3" in diameter in the back body section.
Fill the piñata with small candies, nuts, and toys, or for that authentic Marita feel, lies, deceit, and a Do it Yourself Oilien.

mode

(3) Seal the opening with duct tape
(a substance the real Marita is, no doubt, more than familiar with)

(4) Decorate the piñata using poster paint or old designer clothing.
Knotted yellow yarn gives a nice bottle-blonde hair effect. Don't forget the oilien-fog in the eyes!

(5) Using strong string, rope, or for that authentic touch, piano wire, hang your Marita Piñata by the head (or neck, which ever is more satisfying) in an area away from breakable articles.

(6) Slap your Marita Pinãta with a large stick.
Or a baseball bat.
Or both.
Repeatedly.
