The blue thing seems to be a misinterpretation of the front facing cloud piranha sprite, no idea about the egg thing though. Maybe a weird mulldozer given the dots?
I also just noticed how most of these are based on the figurines, here I was thinking they made a surprisingly nice blue Gyorg sprite

What's that egg thing between Spark and Keese, and that weird blue thing between Iron Ball Soldier and the Moblins? I recognize the others from the actual game. (Octorok, Trap, Chaser, Spark, ??? Keese, Tektite, Leever, Whisp, ChuChu, Sluggula, Rollobite, Peahat, Helmasaur, Like Like, "Spiny Beetle"/Hoarder, Puffstool, "Spiked Beetle"/Spiny, Eyegore Statue, Armos, Keaton, Ghini, Rock ChuChu, Bob-omb, Bombarossa, Rupee Link, Rope, Stalfos, Gibdo, Scissors Beetle, Moldworm, Pesto, Floormaster and Wallmaster, Boulder, Spiked ChuChu, Acro-Bandits, "Moldorm"/Tail, Ball-N-Chain Soldier, ???, Spear and Bow Moblins, Beetles, Wizrobe, Fire Wizrobe, Ice Wizrobe, Darknut, Darknut Red, Black Knight, Madderpillar, Fake Door, all the bosses)

Ahhh, that makes a lot more sense.

It's a turn-based RPG like Final Fantasy or Dragon Quest, hence lack of animations.

Do the enemies not have any sort of animation? That's odd...
Unless this is for their figurines or something. Then again, who really knows with bootleg games.
