"I wanted to do a greenhouse because it represents global warming, and I did some aubergines because if we eat more 'eggplant' and less meat, we could help to slow down global warming. I am vegan, so I wanted to find a way to show veganism through this competition, because I believe it will help ALL the animals if we all cared more about the planet, and going vegan is one way to do this."

"These are my egg creatures. I made the killer whale by blowing an egg, then dying it with red cabbage (it went dark blue). I made the fins and tails from card and glued them on, then painted on the face. For the narwhal, I dyed the egg in spinach (it went grey). Then I used charcoal from our fire pit in the garden to colour it. I used a shell for the tooth."

"It took me about five hours in total to make this!"

"Axel Otl is an axolotl. Axolotls are amphibians that can regenerate limbs and small parts of their brain! Here is one peeping out of a pond."

A BIG well done to some of other favourite entries:
Selena, age 10, Croydon, Ostrich egg

"Dear Eco Kids, This is my competition entry. I made an ostrich, his name is Eggstrich. I used and egg for his body. He is very grumpy . Here is a poem which he repeats each day:
I wish I were a camel,
To moan all day,
In the desert I would live.
I wish I were an elephant,
To spray myself with water,
In Africa I would live.
I wish I were a lizard,
With bright shiny scales,
In the Rockies I would live.
I wish my wishes came true,
So I could be someone else,
Rather than Eggstrich."
Rueben, Eggle the owl
"The egg comes from my grandfathers farm in South Africa. He has Emu’s on his farm and Eggle is one of their eggs. Emu’s eggs are black and smaller than Ostrich eggs. His feathers are real feathers from a guinea fowl. I loved making Eggle and reading all about zoos in your latest magazine."

You've been designing brilliant new contenders for the Astonishing Amazon Animal Showdown – piranhas with jaws that regrow in whole quarters, a hoatzin that ferments its dinner in a throat pouch, a tailless whip scorpion that senses danger through its legs, and a jaguar with one of the most powerful bites of any mammal. Thank you to every reader who did the research and made the case for their champion.
This competition asked you to design a secret egg hidden somewhere in nature, and your entries went far beyond the obvious nests and burrows. Eggs arrived disguised as pine cones, floating on leaf boats, perched on volcano ledges, tucked into cloud cover and even masquerading as chocolate Easter eggs to fool foxes. Thank you to every reader who took up the challenge and thought like a parent bird, fish, reptile or imaginary creature trying to keep their precious egg safe.
