Santo Bugito Episode 09 The Lost Cause, 1995.
"The overworked Carmen and Paco try to go on a relaxing second honeymoon, but instead are disappointed by a catastrophic vacation. Meanwhile, their ingenious friends back home have whipped themselves into a frenzy: they have convinced themselves that Carman and Paco are lost in the desert with broken legs! The crazed search party and disappointed ants clash in the desert with surprising results."
