The Side Crawler, otherwise known as a crab, is a pretty basic enemy in the world that Wonder Boy inhabits.
I loved playing this game when I was younger, and although the crab wasn’t a difficult enemy to overcome, I still find it quite memorable. Somehow, the crusty crustaceans managed to carry coins, necklaces, harps and other items.
One of the interesting design choices was that the original Side Crawler had all of its legs on the sides, and so would only actually be using two of its legs to walk. I decided that rather than change this quirk, I would add in the unused legs in a position that wouldn’t be useful to the little guy.
