COME TO AUSTRALIA ( <-- Click it or you might accidentally get killed.

Redback
Funnel-Web
Blue Ringed Octopus
Taipan
Tigersnake
And a box jellyfish
Stonefish,
Coneshell (The poison thing that lives in a shell that spikes you when you pick it up)
And a big shark (just waiting for you to go swimming at Bondi beach.)

Characters/species are in this exact order of the lyrics, and obviously all these species can easily (and rapidly) kill a human being, and are proud residents of the wondrous nation of Australia. You may have no clue to what this picture refers to unless you see the above link, So go check it out.

I added Toxin holding a taipan and tigersnake because seasnakes are the most toxic snakes in the world, even more poisonous than the two species she is holding; and Glaucer since his species steals & concentrates the most poisonous stingers from the deadly jellyfish they eat, and therefore are even more poisonous. (if he eats those chironex, then he would effectively be the deadliest thing on earth via poison theft xD) Yes(seaslug) mans his coneshell as a lethal harpoon weapon. I may color this later, maybe.
