Neither fishyidea nor 262119 show up in haveibeenpwned's database, so they're at least uncommon. Neither of them look to have much entropy, though.
2x211y doesn't look very random to me. 2 and 1 are consecutive, and there are only 4 distinct digits here. Even if it was randomly generated, a good password generator would probably discard it for being akin to passwords that humans tend to generate. (This is especially true when you impose minimum lengths to passwords. "26219 isn't long enough? Fine. 262119.")
Fish and idea are both among the top few thousand most common words. Searching adjective+noun pairs is going to be much more fruitful than searching arbitrary word pairs, and ideas can in fact be fishy, so it makes sense to guess that particular adjective+noun pair before trying metamorphicidea.
