life
As seen in "Burpless Bean", the camp called all four of Edward's older brothers, who look very successful, to watch Edward in his performance. One appears to be a wrestling type of person with muscles. Next to him seems to be a tall basketball player. The next seems to be some sort of rich millionaire who takes everything fancy. The last one seems to be a teenager sort of brother with zits on his face with a sweat shirt on. Only two of them seems to have an official name which is Mel and Cheasly. There is proof that they have been scouts before him like in the "Great Snipe Hunt" in which Edward explained his brother Mel was a camper and Lumpus seems to throw the same thing every year. They also make an appearance near the end of "Hold it Lazlo" when they (except Alpine) speak. They were voiced by Tom Kenny and Jeff Bennett who also voice Lumpus, Slinkman, and Raj.
