From "Husky Gang Tales" by Phyllis Sdoia-Satz

Professor Lump and Dr. Riaza are the new teachers at the Husky Gang Music School.  They come from the planet Tzedahka.  Professor Lump will be the head of the school's new Department of Extraterrestrial Music, and Dr. Riaza will be his assistant. As soon as Professor Lump and Dr. Riaza arrived, the Husky Gang went to greet them and welcome them to the Husky Gang Music School. In a very short time, the Husky Gang learned a lot about them. 

First of all, Professor Lump (his friends call him Lumm) is blue and Dr. Riaza (her friends call her Rii) is pink.  Both of them have many mouths, eyes, arms, and legs. This helps them play several different instruments at the same time. It also helps them do many tasks much faster than those of us who have only one mouth, two eyes, two arms, and two legs. Lumm and Rii can also make themselves bigger or smaller, so they never have to stretch or bend.

Lumm and Rii speak many languages. When they speak, they hum and ruggle! They also swinkle.  Once in a while when something really great happens, they moogle (but that doesn't happen too often.) They can make themselves invisible, and they blink on and off when they are happy or excited. Lumm and Rii came to the Husky Gang Music School in a farrawwweee. With a farrawwwee, they can travel through time and space to see anyone, anywhere, at any time. Lumm and Rii told the Gang that not long ago, they traveled back in time to 1826, to visit Ludwig van Beethoven at his home in Vienna.
