I notice that though all of the single-element monsters have the same purchase price (300 coins), their selling prices vary widely. Noggin: 12 coins; Kayna: 22 coins; Mammott: 37 coins; Toe Jammer: 71 coins; Potbelly: 133 coins; Tweedle: 255 coins. If one were to buy-then-sell single-element monsters to get this achievement, one would want to do it with Tweedles.
