This riddle made me think of something that I thought was unrelated. So I looked that up and then I think I accidently figured out the answer to this… So I’m going to pass on answering this week because I accidently cheated.
Though, if it turns out I was wrong I think I’ll be happy about it.
For people asking why this is the answer:
Hippopotamus comes from the Greek “hippos” meaning “HORSE” and “potamos” meaning “river” (“riverhorse” very cute).
Homer (not Simpson) was an ancient Greek poet best known for writing the Odyssey.
