The Summer Sensations is a music band featured in the episode "D.W. Beats All." The band consists of Arthur playing keyboard, Buster playing tuba, Francine playing drums, and Fern playing the flute. They practiced in Arthur's garage, and only performed at the Summer Serenade music festival.
The name was most likely based on the concert they were going to play at called the "Summer Serenade." This was a name that was settled on, because the names "U Stink" and "We Stink" were already taken by them in the past.
