Tubby Wubby Pony Waifu. A surprisingly sweet love song, especially for one about a magical blue pony and an evil monkey in clown make-up.
I don't know why, but I find this comment from this video strangely heartwarming: "No RDP cheating! RDP will be made on the basis of love and whatever other emotions we keep using. Gorillas and stuff. Gorillas are emotions. I feel strongly about Gorillas. RDP is not for sale! I will use the voice, though."
"Sinking Ships", a song about not letting life get you down. Especially heartwarming (And a bit tearjerking) considering this is the last Rainbow Dash Presents.
