Camping Out (1934)

Mickey and Minnie get swarmed by mosquitoes while camping out!

The gang is sitting around their campsite when a mosquito spoils their fun. And then he gets hundreds of his friends and they really cause trouble. Horace squirts some with molasses, which helps a bit. Everyone retreats to the tent, where they still get stung but can fight back a bit, eventually trapping all the mosquitoes in a pair of bloomers and sending them on their way.
