I did my own zombie concept for fun for Massive Black's Zombie Playground. After brainstorming some possible character ideas, I thought it would be cool to see a crossing guard zombie who used her trademark stop-sign as her weapon. Not only that, but when she needs backup she's got her whistle to summon the help of other nearby zombies. In order to beat her in battle you would have to figure out a way to snatch the whistle off of her so you can take her down one-on-one.
