Shelby finds a note in his lap, which explains that the severing of his lower part meant that he has a new brother now, and his name was decided to be Butty Butterson. Shelby asks who he is, to which the creature could only blow a rasp. He is astonished as his lower part starts to move. Shelby falls unconscious and the scene changes to him waking after a long time. When he fell, he says that he is quite hurt, and finds that his lower part of body is severed by a string in mid-air when he fell. He performs his parkour by jumping on a pole, then on the roof, but he is pulled down because he could not hold for long. The scorpion asks what will he do, to which he replies he will do parkour. This makes Shelby jealous, and he says he can do it. Everyone gathers round the bug, and a scorpion starts to compliment it by saying it was the best bug in this party. Everyone is having fun, and Shelby asks a Dancing Bug to "shake it." At first he was starting to disagree, but then he agrees and starts to dance, which makes everyone awe-struck. As he sees inside, there seems to be a bug party going inside his viola, and it's also seen that Shelby is hosting it. As soon as he starts to play, someone is heard shouting inside his viola which startles him. He starts this and follows its oscillation to play his viola perfectly. The view goes inside the tree fort, and Jake is seen to be starting a metronome.
The episode begins with the night view of tree fort. Shelby accidentally gains a new brother, who he inspires to become a great hero.
