When you find yourself trying to remember a show (or any works) that's on the tip of your tongue but just out of reach, come here - the collective brain of the TVTropes community can probably help. Post all the details you can remember (examples help). If you're looking for a trope, head over to Trope Finder. Have general questions about tropes? Visit Ask The Tropers!
The first game might be any of the Final Fantasy Legend titles. A recurring theme is that monsters have meat as a random drop, and a party member can eat it to change form or increase stats, depending on the mechanics of the specific game. Here are some extra details from the Final Fantasy Wiki for the trilogy.

Could that be the third one? I have the same memory, so I know you're not making it up (unless we both are). If not, was it possibly a loading screen for Toe Jam and Earl...? I remember playing that with my cousins for hours, and I know it had dancing hula girls...
Regarding the second one, can't help you with which compilation it appeared on, but the smiley face game may have been Arcy 2
.
Hmm... if both of those are games on it, there's a decent change it's "GCW Games for DOS"
, although that link takes you a discussion with someone else in search of it. It might be the one here
but I can't download the ISO to check right now.

Does anyone know what the following videogames are? I have fond memories of them, but just can't seem to find them.
I'd be really grateful if anyone knows what these could be. Thank you so much for your time~
