These changes were all aimed at making the show "appropriate" for kids, and to prevent even the slightest appearance of "inappropriate" content, imitable violence or sexuality. The character Dot was considered too sexualized by the BS&P even though she was "never one to expose much cleavage" so the animators were forced to make her breasts less curvy and form them into a lumpy "monobreast", as lightly referred to by the staff. However, starting with season three, after severing ties with ABC, the "monobreasts" of all adult female characters were replaced with more anatomically correct versions. In another case, the word "hockey", as well as the sport itself, was cut in some countries as it was supposedly used as a vulgar slang term there. In the episode "Talent Night", one scene of Dot giving her brother Enzo "a sisterly kiss on the chin" was cut due to BS&P's fear of promoting incest, an insinuation which Pearson described as "one of the sickest things I've heard." Each installment of the first season was a self-contained episode except for the two-part finale. When the User loads a game, a game cube drops on a random location in Mainframe, sealing it off from the rest of the system and turning it into a gamescape. Bob frequently enters the games, reboots to become a game character, and fights the User's character to save the sector. If the User wins a game, the sector the cube fell in is destroyed, and the sprites and binomes who were caught within are turned into energy-draining, worm-like parasites called nulls. When this happens, they are said to be "nullified". In the United States, the show was aired on the ABC Network and had to comply with Broadcast Standards and Practices. This was lampooned in "Talent Night", where almost every act for Enzo's party is banned by Prog Censor Emma See and the Small Town Binomes sing their hit "BSnP" ("It's fun to play/In a non-violent way"). The second season was initially as episodic as the first but later featured an extended story arc that began with the season's fifth episode, "Painted Windows". The arc revealed that Hexadecimal and Megabyte are siblings, and introduced an external threat to Mainframe: the Web, which was set up in fearful mentions in "High Code" and "Painted Windows".
