I searched in the web for this games, but I didn't find them. Please, help me

The first:
It was a flight game from middles 90's, I guess... With top down perspective (non-first person) and it have great graphics (3D if I don't remember wrong. In fact, I'm doubting that it was a DOS game

Second:
It was a side scrolling game from earlies 90 with living colours... You're a green fluorescent man (or alien) with a gun and you start in a forest... No, It isn't Cosmo's Cosmic Adventure

Third:
I think that you'll have no problem with this... I'm searching for Oscar... The side scrolling that you're a squirrel or something with red hat... I see it on a thread, but there isn't the link were i can download it...
That is all... I hope you can help me... I searched for this games on the page and this forum, but nothing... how odd! But i remember that I played this games, I'm sure... Well, thanks anyway for your attention

P.S.: Forgive me if you don't understand some words... I don't speak english very well...
