除了做饭外，大厨也热衷于唱歌——他写了首名叫《臭裤子》（Stinky Britches）的歌，结果却被占到了艾拉妮丝·莫莉塞特的名下。他是以1970年代的黑人歌手艾萨克·海斯和巴里·怀特（Barry White）为原型的。他经常用唱歌的形式为孩子们提供建议，但常常兴奋地唱出有关性爱的歌词。然而像许多早期剧集中的角色，他唱歌的戏份受到了缩减并且不经常唱歌了。到他去世为止，他已经有整整4年没有唱过任何一首歌。
另外有一些人认为，海斯是在山达基教的压力下才被迫离开的。然而根据最后的报道，海斯并没有离开剧组，因为最初的声明是由一个没有得到他授权的人发布的。在2006年1月4日，海斯还为《南方公园》有争议的幽默风格向Onion公司的AV Club、XM公司的Opie以及安东尼秀（Anthony Show）作出辩护，值得注意的是，海斯虽然对剧中对山达基教的描述不满，但他“理解（马特和特雷）在做什么”。据报道海斯在2006年1月中风，并没有能力做出重大决定。

In South Park: The Stick of Truth, Chef is revived as a Nazi Zombie by Clyde. The player referred to as "Douchebag" must fight him as a penultimate boss. It is revealed that he has been stitched back together, however, his skin has turned green (like most zombies in the game), the visible scars and gashes from his brutal death still remain, and his old clothes are tattered (as you would expect). He will quickly switch between his old voice and the Nazi outbursts common among those exposed to the green goo. His voice lines are similar to being replayed from an old episode, much like "The Return of Chef", this is due to how the original voice actor having passed away 6 years prior to the game's release, when making his old voice lines, he is still his old self, showing regret for him being forced to attack the boys, but this is quickly stopped by Clyde, who quickly covers him in the green goo.
Zombie Chef's abilities include: "Chocolate Salty Balls" involves him pulling out said balls from the gash in his stomach and will inflict gross out if not blocked, "Hello Children": where he attempts to bite the player character (but mashing the corresponding buttons when shown can resist the attack). Or he can use his spatula as a Melee weapon dealing a large amount of damage if it is unblocked (especially to Jimmy or Cartman).
When the player takes Chef's health down to 1 (from a rather large 73,476 if you are level 15), Chef will fully regain control of himself and proclaim "Children! Everybody! I'm back!", before Clyde will throw a Molotov Cocktail at Chef, causing him to violently burst into flames and run around. The player will charge up and release a powerful fart, to which Chef gets caught in the proceeding fireball, killing him and causing him to re-sustain the brutal injuries that lead to his original death, albeit him now being horribly charred. If the player fails to do this quickly then Chef will set the player and their buddy on fire unless they have any shields. Once they have no shields then they will get fire damage and will die soon meaning that they will have to restart the game from the last checkpoint.
