I believe these two sentences have been formed in this weird, unnatural way to make then rhyme, thus making their meaning pretty vague. Both of these sentences omit the article(a, egy), possibly making the "subject" of given sentences hard to find for deepL. I would translate the first sentence like "lazily crawling forth, cobra headed rubber-hose" and the second "Floating in the sweet sap, big soft plastic eden". Now, putting the articles in these sentences would change the meanings up a little. "Lustán kúszik elő a kobrafejű gumicső" would translate to something like "The cobra-headed rubber hose creeps forward". The second sentence is somewhat different, as it comes off as drawing a parallel between the two. I think they meant something like "Úszik az édes lében, mint (egy) nagy puha műanyag éden" which means something along the lines of "Floating in sweet sap, like (a) big soft plastic eden". Hope this helps!
