Can anybody identify? There's A BUNCH of them here where i live (brazil)

I don't know anything about slugs but they are always so pretty, can i touch them? Thank you so much!

I live in vegas, and for the past 20 years I have lived here I did not think we had slugs. It seems to hot and dry for them here. But..! During one of our recent storms, I walked outside to enjoy the rain, and came across this little guy! At first I didn’t know wtf it was, and my first conclusion was that it was a lizards discarded tail that had gotten soaked in the rain. So I decided to poke it with a leaf. You can imagine my surprise when two eyes popped out and started looking around! Then I was absolutely entranced by it! I watched him for about 40 minutes, which you can imagine was a whole lotta nothing considering its a slug. Anyway, he has been frequenting my walkway ever since I first saw him and im absolutely obsessed. I think hes so cute and so interesting. The other night I left my house to go pick up my boyfriend and he was halfway up my wall! I was gone for a little over an hour and when I came back he had made it back on the ground and halfway back to his home in the rocks! I can’t imagine a world so slow. Lucky slugs! Now every time i leave my house I check the floor so I dont accidentally step on him. Tonight he was out again and looked to be heading home for the night, and so I looked up what slugs eat, and gave him a little slice of cucumber. He went right towards it and started chowing down! I hope a full belly helps him keep warm now that its colder, if thats even a thing for them. Im so happy that I saw him!! Its been so fun having a little slug friend. Also if anyone in here can tell me what kind of slug he is that would be great! I know it’s a garden slug, but wasn’t sure if that was his entire identity. Are their variants? Let me know! I’d love to know more about him.
