From BZPB Spin-Offs
When someone logs into the chatbox, they may choose to make sure that everyone notices their presence. This is usually done by creating a dramatic entrance, usually with explosions or an epic song.
Shroom rarely comes onto the chatbox without a dramatic entrance, even if no-one else is logged on in the first place.
DRJ, however, hates dramatic entrances, because they usually involve typing the lyrics to a terrible song in capital letters.
