On one hand, it's almost a relief to have some semblance of his normal powers back after so long. On the other, things should not reshape themselves like that on the mortal plane!

So before he tries to use it for anything more ambitious than that break room house he apparently made - which hopefully his employees enjoy because it's in the style of his Neighborhood and thus actually pretty cheerful and nice - he is indeed gonna roll to test it out. Solely on small-scale things! He'll try focusing on a particular item, like a cup of goddamned actually frozen yogurt, and see what happens.

.....if the yogurt fails several times in a row, he may decide to try something "scary" and summon a penis flattener.
