There are several items you can find under the microscope. It’s what keeps the paramecium complex alive: music!
The bongo’s (left), the piano (lower left), the glove (lower right) and the trumpet (upper left) should all be take to the excentric (piano and gloves), hindu (bongo’s) and sleepy head (trumpet) in the center. Give them the instruments and they’ll start playing a modern version of Beethoven’s 5th. But no one can enjoy their music because when you go a bit to the north you can see that santa is stuck and blocking the way. Use the lightning bolt to zap santa and music can flow through the complex.
By the way, the blue cup (bottom) can be taken to the soldier with the big spike just below the musicians but there’s no real use.
