This is a peppy song, with a sad yet cute meaning. It's about a goldfish named penelope, who the person in thought is concerned about dying, struggling, etc. This is shown in the lyrics "don't want to see you floating upside-down, on the top of your bowl when i come down to visit you," and also "deep into the forest, let you feel the raindrops soak into your red scales." and lastly, "eliminate the need for water. I think the song is talking about a child who really loves his goldfish. Possibly a childhood story of Rob's.
