Are there d20 conversions for the following monsters from the 2nd edition Monstrous Compendium:

Eels (Electric, Giant, Marine, Weed)
Fish, Giant (Catfish, Gar, Pike)
Giant Crayfish

 

[the Jester]

I remember the giant crayfish in the Tome of Horrors, and maybe some of the eels too?

I've done the giant gar myself, will try to post it for you tomorrow.

There's a giant pike in the ToH2, but it is technically not a conversion.
Also, I think a recent Dragon had a giant gar... ah, #321.
