In the poster released this time, the "bathroom singer" crocodile Lailai is lying in a bathtub full of bubbles, holding a shower head as a microphone, and singing with an intoxicated face. In terms of temperament, Crocodile Lai Lai can definitely debut in the C position. In addition, Lailai's tail holds up the "audience" little rubber duck, the clear sky outside the window, and the bubbles dancing in the air. The combination of the pictures can be said to be full of fun and fill the room with joy.

The film tells the story of the Prim family who move into a new home as tenants, only to discover that their roommate is a singing crocodile. This little crocodile who loved bathing and singing was forced to live together with the Prim family. Lailai looks rough on the outside, but he is lively and kind, loves life, and hopes to share happiness with everyone through his favorite music. And he and this family went through many farces, and eventually established cross-racial friendship and family ties.
