Dr. Yang (Dr. Yang)

The role of grandpa goat. However, doctors from science, archaeology and other professional fields often make very strange inventions and less useful things. I often take Qiao Hu on outings with them or something. Qiao Hu is regarded as an eccentric person, a professional who provides convenient services, and is not respected. Self-proclaimed "the world's first scientist."

Tommy(トミー)

Qiao Hu's cousin. A unique way of speaking with English words. The initial role in the English teaching of "こどもちゃれんじ". Animation debuted in the 53rd sentence in the second year of broadcasting, and it appeared normally for some time. I also played with friends in Qiao Hu, but later I stopped playing. Since then, it has also appeared in OP animation, but now neither the TV version nor the online version has appeared. It can also be called the original "こどもちゃれんじ" English textbook, and Tommy did not appear. About the reappearance in comics, it is uncertain. Some of them appeared in the movie version しまじろぅののぉともだち ".But it is out of print.

These two are probably the most important.
