In Sunshine, Bob at first appears as a simple black-and-white drawing of a stickfigure with a head, torso, and wields a mic in his left hand. Bob is seen to be happy in this song.

In Withered, Bob is seen to be irritated by the look of his face with a black smudge between his eyes and lines next to his head to show how mad Bob is.

In Run, Bob's entire body is completely black and his eyes are replaced with hyper-realistic eyes. Bob also no longer wields a mic.

If happy mode is selected, Bob in Run will lose his outline and have a crudely drawn smile on his face that constantly changes between frames.

In Trouble, one of the new songs in Bob's Onslaught, Bob is in his normal form, however a part of hell Bob (presumably the remnants of his form in Run) covers parts of his body, including half of his face and his arm. A realistic eye also remains on the part of his face covered in black and his microphone drips presumably the black substance.

In Onslaught, another one of the new songs in Bob’s Onslaught, Bob‘s body becomes completely black once again, but has a different appearance than his appearance in Run. He has white eyes and a white mouth, which are made from a mysterious goopy white substance of some sort. Bob’s arm disappears once again, but this time, it is replaced by a black colored hand that has 4 fingers, and said fingers are covered in the white goopy substance mentioned earlier. His body also appears to be ripped and torn. Upon closer inspection, Bob appears to have blood on his neck and on one of his fingers. The reason why Bob is in this state is probably because of what happened during the very end of the song, "Trouble".

Boyfriend compares Bob to Minecraft YouTuber Dream due to the resemblance of Bob to Dream's avatar, to which Bob is made visibly upset.

Gameplay Mechanics

• During "Run", Bob will occasionally jumpscare the player by covering the screen with a big black eye. During the jumpscare, the screen will occasionally shake and hinder the player's vision. The game window will also move around and shake, and if the player has the window expanded, the game will minimize it before shaking the tab.

  • The music will still continue during the jumpscare, forcing players to remember what note was used during that part of the song and when to use it.

  • The jumpscares become more frequent at the end of the song, accompanied by an almost impossible barrage of notes that will likely crash the game.

  • The player will lose about 15% of their health when this happens.

  • This mechanic can be turned off.

• Dying in "Run" leads you to "bob is mad".

  • There is an audio file at the bottom named "bob theme". As it turns out, this is actually "Why you acting sus?" but reversed, slowed down and heavily distorted.

  • In the "bob is mad" chain, there is something that reads" "theimpo" in front". (supposed to say "When the impostor is sus").

  • This mechanic can be turned off, replacing it with Boyfriend being impaled on a stalagmite if he loses.

• If you press 7 during Run, a static screen with the text "You can't run" will show up along with a unsettling sound. The sound that plays is actually just Ugh, but played on a violin and heavily slowed down.

• Like for Run, pressing 7 during Onslaught will show a static screen with the text "can't run while you are having fun" with a loud and unsettling sound. The sound that plays is named "FUNFUNFUNFUNFUN.ogg", and it is a heavily distorted and slowed down version of the American version of Sonic CD's boss theme.

• After Onslaught's cutscene, a website will show up showing an image of a hand flipping the bird. The website is named "bob says fuck you".

• In Onslaught, a large number of things occur.

  • If you hit a black note or don't hit a lavender note, your health will drain rapidly, and faster if you hit or miss multiple in quick succession.

  • Advertisements may pop up and block your vision, similar to Cheeky. One even says "We didn't know you had this idea first cheeky sorry :("

  • The note strum goes invisible at certain parts of the song, forcing the player to guess when to hit a note.

  • If the game is windowed, the screen will move around in a infinity sign, and it will move faster as the song progresses.

  • The notes will start to spin around in a circle, being distracting and confusing the player. This gets faster as the song progresses.
