The frog's personality also began to develop. As the series progressed, Flip became more of a down-and-out, Chaplin-esque character who always found himself in everyday conflicts surrounding the poverty-stricken atmosphere of the Great Depression. Owing to the influx of New York City animators to Iwerks's studio, such as Natwick, the shorts became increasingly risqué. In "Room Runners" (1932), Flip, out of cash and luck, attempts to sneak out of his hotel in order to avoid paying his past-due rent. Another gag has Flip watch a girl taking a shower through a keyhole. In "The Office Boy", released the same year, Flip tries to secure a low-level office job and meets a shapely secretary. At one point in the short, a mischievous mouse that Flip tries to apprehend scoots up the secretary's skirt. In "A Chinaman's Chance" (1933), Flip and his dog track down the notorious Chinese criminal Chow Mein. While investigating in a Chinese laundry, Flip stumbles into an opium den, inhales the stuff via opium pipe, and begins hallucinating.
