Here is the next question:
What popular singer released, in 2013, all of the following:
1. A song that includes (in the actual song, not the title) the title of one of Fred's songs.
2. A lyric video that includes an animal that is of the same species as an MRN puppet.
3. A music video that includes an animal that is of the same species as an MRN puppet.
4. Another music video that includes a different animal that is also of the same species as an MRN puppet.
Note that #2, 3, and 4 are all referring to different animals, and that none of them are referring to the song in #1 (although #2 and #3 can be from the same song, #4 obviously is not).
