Mail from Space - Ten-chan Arrives! - Mrs. Swallow and Mrs. Penguin

Sinopsis

A peach falls from the sky, in which Lum's cousin, Ten comes out for a visit. He is capable of breathing fire and is an instant enemy to Ataru. Ten feeds alien candy to a swallow, making it grow massively in size such that it looks like a penguin. Its appearance in school is just the start of a full day of panic.
