For Halloween this year, both kids wanted Minecraft costumes. Denton went as King Creeper (his usual Minecraft skin), and George wanted to be a regular creeper as his minion.
The costumes got mostly finished this year; I ran out of time while painting the pixels on the shells. But a good time was had by all, and the kids even got to attack a Steve while trick-or-treating. Which is to say, they stood there and hissed at him while 'Steve's parents admonished him not to whack my kids with his sword (much appreciated).
