This fixes a crash when the Hock-A-Loogie minigame ends, when
buildDrawList3() would previously try to draw every object, even ones
where 'anim' was null which caused it to crash.
I don't know if this fix is exactly what the original did, but it seems
to match the original behavior when I've tried it in Wine. I've tried
both the standalone minigame, and the minigame as it appears in the full
game.
