Again I struggle with the tiny, tiny text.

As for "M-slave" (M奴隷), it seems to have some connotation of masochism.

しょ…小動物が喋ってる？

ちょれとちんかいいちのびしゃも (I think)

The M is for masochism, yes.

the second looks more like ちょれとちんかい　いちのびじゃぞ to me. Maybe somethingと深海　生き延びたぞ?

I think it's
「ちょれとちぇかい
いちのぴじゃも」
→　「それと世界一のピザも」

Haha, I can see that being right. It does fit more with the theme of this comic. :)
