School Sandwich of the Ostrich Cat

In the school cafeteria, a bold and mysterious assassination attempt has taken place - sandwiches prepared for breakfast have been brutally bitten by an unknown creature. Loud hungry children are besieging the snack bar attendant. The reputation of her cat... Leo, as white as his fur, is about to suffer. Candy wrappers rustle on the floor, and the portrait of the deputy principal on the honor board has been overgrown with green mustaches... Who is the true culprit behind these sinister events? Whom does Principal Ivan Ivanovich hide in his closet? And most importantly, what connects Pirate Archibald and Izolda Karpovna? Only the famous Ostrich, a cat and detective, who is assisted by his faithful companions Tuzik and Tungus, as well as the curious crow Karlovna, can untangle this knot. And anyone who stands in the way of the brave detectives is to blame themselves.
