Lyric discussion by tom.t.walker 

"He" and "His" is capitalized mid-sentence, which is grammatical standard for pronouns referring to God. I assume these capitalizations appear on the original liner notes, as most of the online lyric reproductions have them capitalized too.

The rivers are full of crocodile nastiest And He who made kittens put snakes in the grass He's a lover of life but a player of pawns Yes, the King on His sunset lies waiting for dawn To light up His Jungle as play is resumed

The song is likely pointing out the irony of "He" (God) who made [cute] kittens also made [mean, ugly] snakes. We are entertainment for the King in his jungle.

The line "I'll write on your tombstone, 'I thank you for dinner' " likely refers to survival of the fittest. Kill or be killed.
