Many of these are likely near the bottom because Sporcle counts spelling and they have tricky names that could cause a player to give up on them, particularly Lickitung, Qwilfish, Beheeyem, and Fezandipiti. Others with tricky-ish names being near the bottom of their respective lists corroborates this (Exeggcute/Exeggutor, Snubbull, Lickilicky, Amoonguss, Pyukumuku, just to name a few) so I wouldn't put my stake wholly in that.

I agree with this.

Another thing that's worth noting, although you might consider it a valid part of a Pokemon's memorability - Pokemon tend to be remembered better when they are clustered in a group. If you remember either Huntail or Gorebyss, you are likely to remember the other, as well as Clamperl. A major thing that most of these mons share is a lack of clustering - Qwilfish, Chimecho, and the baby mons from gen 4 (including Mantyke) are all EXTREMELY guilty of this, which makes them difficult to remember when putting together a Sporcle list because there's nothing to hook onto to guide you to remembering them.
