WHO IS DR. SiMSiM?

Dr. Simsim always wants things organised and in their place. He usually takes the lead in visits and has a soft heart towards his mates because he wants to teach them everything! He easily loses his temper but it is so easy to calm him down again.

Sometimes he forgets he is in a leading position and becomes crazy and begins to sing and dance spontaneously, then he remembers he is a prestigious doctor!
