Itch and the Fatberg removal

This is Itch. As
you would expect from a roach, Itch enjoys in eating anything. Lately he’s been
living in a sewer because of financial problems. Gratefully though, he’s able
to eat whatever he wants in his new home. However, because of Itch just eating all
the time, he doesn’t pay attention to the fatbergs forming in the sewers.
Blocking off his exits to the world above. It’s up to Itch to eat those
fatbergs blocking off his exits or it’s kaputs for him when the sewer water rises,
drowning him in the process. In order for Itch to eat those Fatbergs though, he
needs to eat everything in a sewer room. Otherwise  he won’t move on
