There are some levels I have not played yet in Alpha 5, and there are some zombies with weaknesses not mentioned like the Mega Gargantuar's helmet will now fall off and can be taken by Magnet-shroom.
Since Part 3 is not yet out, it will remain hidden for now, I suppose. But when the Mega Gargantuar is introduced, the dialogue will explain the Mega Gargantuar's weakness.
(there's probably more hidden things Eclise did not discuss in their almanac entries)
