В реке было много животных и много шума. Затем пришел лев и животные стали тихими. Лев шел медленно к реке. Он смотрел на воду. Он видел свое лицо в воде и улыбался. Ему нравилось его большое сильное лицо. Лев положил сильную лапу на хвост мышки.
- Кто здесь главный? - спросил лев
- Ты - сказала мышь нерво
- правильный ответ - сказал лев
Лев увидел слона 
Хэй ты! Большой нос! сказал он
Слон не посмотрел на льва
Большой нос! Я с тобой разговариваю! рассердился лев
У меня нет носа. У меня есть хобот сказал слон
хорошо. Большой хобот, кто здесь главный? 
Слон не ответил, но его большой длинный хобот быстро двигался. Он поднял льва и бросил через реку.
Хорошо, хорошо сказал мокрый лев. Ты злишься потому, что не знаешь ответа
