Having big emotions that take over your body can be a scary feeling, especially when you don't have the tools to calm them down. 
This book shows what can happen when you push your emotions deep inside of you and bottle them up instead of expressing how you are feeling.

If too many emotions are bottled up, eventually they will explode more fiercely than before. The emotions and feelings we bottle up, don't go away.

They can stay there until we cannot contain them anymore and everything will bubble to the surface. 
This book offers a visual way for children to see just that. Uni the Unipig ignores his feelings and eventually reaches a tipping point. 
His magic bottle that fills up every time he bottles up his feelings eventually explodes. What will he do the next time he is faced with his emotions?
