Walmart offers the Minecraft Papercraft Hostile Mob Pack, model no. 16703, for $5.40. (Amazon offers it for about the same for Prime members with orders of $25 or more.) Opt for in-store pickup to avoid the $4.97 shipping charge. That's the lowest price we could find by $6. It includes over 30 pieces, including gravel blocks, creepers, witches, zombies, and cave spiders.
