This was Theme Week Bugs.
What two kinds of insect are associated with Buzz Buzz over the course of the game, in dialogue or otherwise? Bees and bung deetles. Uh, dung beetles.
Say that you proceed through the game, that you acquire the melodies in order, and that you acquire Magnet Hill as soon as you're contacted by Mr. Spoon. What's the last enemy (that looks like an insect) that you gain the opportunity to fight? (Note: neither spiders nor slugs are insects for the purposes of this question.) The Filthy Attack Roach (in the Fourside sewers) or the Master Criminal Worm (although its name isn't "insectoid", it does resemble the Criminal Caterpillar, which is an insect).
Which insect has the most enemies (including one boss) based on it? With 4 enemies (including the boss), the ant.
Aside from the boss, name two of the enemies referred to in question 3. The Black and Red Antoids, and the Gigantic Ant. (The Titanic Ant is the boss.)
What rare, 1/128 item affects only insect enemies? XTerminator Spray.
