Beach Picnic (1939) on Netflix

Donald Duck is at the beach and tries to ride a rubber horse. He notices Pluto sleeping at the shore and decides to have some fun with him by sending the rubber horse over to Pluto which completely mesmerizes him. Meanwhile, a tribe of ants abduct Donald's picnic lunch. Donald lays out fly paper to stop the ants. Pluto follows one of the ants and, of course, he and later Donald become enmeshed in the fly paper.

Donald Duck and Pluto go to the seashore for a nice quiet picnic. But a colony of ants, appearing as a band of painted Indians, swoop down the chocolate-layer cake, and start to haul it away by pieces. Meanwhile, Pluto gets tangled up in some flypaper which Donald has placed to capture the marauding ants.
