Apathetic Panda is anything but apathetic. He's actually very emotional and usually thinking about food or sleep, but he never gets angry. He's just a chill cool panda with a big heart.
The sticker collection is available on iOS as an iMessage Sticker Pack and can be purchased for $0.99. (Link to App Store)
I do have some ideas planned for updates. If you have an emotional state that isn't currently featured, feel free to send me a comment using the form on my contact page.
