Bonk 2. However, recently I've been highly considering recomposing the Bonk 3 CD soundtrack(no fluff, just do the tunes without extra mixed in), to make it sound like it's using a souped up version of the sound engine from the first 2 games. I kind of wonder, how hard it would be to hack Bonk 3 CD so that I could also make renditions of the bonus stage tunes, & maybe even the end stage, boss defeated, & invincibility tunes. However, those last 3 might be totally impractical, as they would required extra loading that might get annoying, especially the invincible tune. IF I was able to do those however, I probably wouldn't do the tunes from Bonk 3, but rather, redo the ones that are in the first 2 games. Those tunes never should've changed thruout the series IMO.
