Collateral Damage Studios is a local illustration studio best known for their anime artworks. You might have seen some of their art on buses, lamp-post banners and even in the supermarket before. As CDS is developing a colouring book featuring the local Singapore fauna as kawaii anime girls, they have released a couple of pages for anyone to download for free.
Once you have the pages downloaded, you can print them out and colour them in any way you want it! Give the otters a lovely sheen of rainbow!
