Porky in egypt (1938)

Porky is a tourist. He's missed the main camel, so he rents one of his own. Both of them are soon overcome by the hot desert sun; the camel starts hallucinating, and marches off, playing the bagpipes. Porky sees the camel swimming in a pool, but it turns out to be a mirage. The camel eventually recovers enough to bring both of them back to town, where Porky goes mad.
