Chain Chomp with Log (42, rev. 0)
Starting revision
Category 'Uncategorized', known
It is possible for nybble 11, value 2 uses a sprite set that needs to be selected. That could explain the crash. I haven't tried this with the original unused level 3 to confirm.
It might try and load a file that does not exist - try loading the debug mode after it crashes or try using this:

Data files:
• /enemy/w_pile.nsbtx
• /enemy/wanwan.nsbmd
• /enemy/wanwan_chain.nsbmd
Sprite fields:
W/Chain Chomp: list at nybble 11: 0=No Chain Chomp,1=With Chain Chomp,2=Crash. 0 and 2 are Unused
