This has confused me for a long time: Are Spinies more closely related to Buzzy Beetles or Koopas? Looking at descriptions implies they are spiked, quadrupedal Koopas, but in-game sprites and models generally more closely resemble Buzzy Beetles. In addition, in a Mario Party 8 battle minigame (of which the name escapes me temporarily), a Lakitu throws Buzzy Beetles onto the playing field, rather than Spinies.
