Try to get close to Alex Brightman as possible.

Fizzarolli is a theatrical demon, with a fast-talking demeanor and a crude sense of humor. Extremely vulgar in nature, Fizzarolli constantly makes sexual jokes and puns, to the degree he pairs up with Asmodeus in openly condescending sentimental relationships and offering lewd suggestions.

Judging by Blitzo's comments about Fizzarolli being an overrated sellout, and his overwhelming presence on Mammon-sanctioned products, Fizzarolli does not seem to have an issue with his image exploited by corporate marketing, possibly because it makes him highly popular.
