Theo - the theatrical captain

Theo and his whole family are theatrical mice. They settled in the theater a long time ago, but have managed to remain almost invisible to people - right until Theo decided to make a small gift for his sister. However,... to do this, he had to chew a huge hole in the skirt of the prima ballerina. And now, it seems, the performance is over. And the mice in the theater as well.
At the end of the book, there is a surprise for the readers: figures on bases, musicians and their instruments. You can assemble your own orchestra and continue the theater game - the theater curtain is depicted on one endpaper, and the device of the theater in a cross-section is on another.
For younger and middle school age.
