ニャン太のおたんじょう日は火事さわぎ！
The film tells the story of Nyanta, whose birthday party is today. On his way home to prepare for it, he scolds some other kids for irresponsibly playing with fire. When Nyanta gets home, he agrees to look after his mother's cooking while she's away, but a prank set by the same kids from earlier turns into disaster as it causes a fire in the kitchen.
