Rhubarb is a strange child. Even the way she came into our world is strange – she grew on a rhubarb stalk. She looks exactly like other children, but has special powers… She can become invisible, for example. She also speaks to the Pink Fish, flies on a bat and never forgets anything. That is also why they have chosen her on the far away Isle of Memory to save the world. Rhubarb doesn’t have to think for a second and does exactly what is needed. She experiences many adventures, invents a global competition and in the end also helps an old steamship and its captain. Rhubarb is unique!
