A kawaii cute blue happy hippo! This design started off life as my 2019 MerMay drawing challenge sketch for day 28, but I liked the design so removed the mermaid tail and added it to my designs.
Where you can buy online
You can find the design on t-shirts in most stores, but also on other products depending on the store (e.g. hoodies, mugs, stickers, notebooks, phone cases, greeting cards, cushions, socks etc).
