EV1 The cake was just a long rectangle sponge with cream and jam ein the middle, i got some ready made green icing rolled it out, then used black icing to make the mouth and eyes and bits on the legs.
pretty basic but it did look quite good.
i made a creeper and enderman halloween outfits they should be in my profile pictures if you want to have a look which ill use for decorations at the party,
hit the creepr game .. basically couple of box's paint green, do the faces.. they then have to hit them down with a bean bag. who ever gets them all down a small prize/sweety.
if you google minecraft templates you can print them out and build little cardboard figures.
stick the mouth on the creeper green card/paper. have the eyes on it but cut out a template of the mouth with bluetac on the back.. basically liek stick the tail on the donkey..
ebay should have minecraft decorations/ass liek plates cups etc if you wanted to do that, but im going to stick with green plates. black cups that ill stick some white eyes on to to make them look like endermans.
also balloons.. green balloon you can draw the creeper faces on to them.. or black ballon stick white rectangles for the eyes.
