Jungle theory

Just realized that a lot of the Jungle creatures have Circle-Like Signs on their Bodies! Here some examples! [(http://imgur.com/a/SPPyl#wFR4zIb)]

You can see some in the Red side jungle as well!!!

Even Maokai has similar signs.Could this refer that There were Sentinels and Bamblebacks at the Blessed Isles?

I'm pretty Sure Daisy has some Signs as well But I couldn't find a picture of her :/ What do You think about these shapes is it Random that they are at jungle-forest related creatures? Has something to do with Magic? I love That Riot is hinting us more and more about the Lore and their updates by these little things!

Have a nice Day! :D
