My guess is for presentation and fame. Since Spamton was a [hochi mama] turned to a legitimate business”man” with this secret only revealed to Tenna (cause pipis). All under the influence of Friend (Pizzapants).
Since a joyful boy is far better for the advertising than a crying girl.
Keep in mind that Everyman is disguising himself too. As the employee of every company. And Everyman uses this strategy in chapter 4 to put on a dress and deliver Pizzarina’s Michael-face cookies to Bratty and Nice Cream.
So Eram hasn’t been using her true form for her entire career until she meets with Michael before he becomes FRIEND.
