Matilda is admiring a butterfly. The pigs have the idea to create a replica butterfly to distract Matilda from the nest...
On an extremely hot day, Matilda is cooling herself and the eggs down in the heat using a piece of white cloth. Her attention is caught by a butterfly, fluttering around her. It briefly spins, as a stunt, and Matilda imitates that. Then the butterfly begins to cool her down, using the wings as fans. Satisfied with this, Matilda waves goodbye to the butterfly as it leaves, and continues to cool the eggs.
In a bush, three pigs in a stack, with the one at the bottom sweating (Corporal Pig on top) spies on Matilda, distracted by the butterfly. Corporal Pig gets an idea and decides to make a fake butterfly to distract Matilda. Corporal Pig produces a fishing rod, swiftly crafts a butterfly made of sticks, leaves, and paint. The 'butterfly' goes over to Matilda, and admires the butterfly again. However, she becomes hot doing this, and as a desperate attempt to keep Matilda's attention, one of the three pigs vigorously shake the rod, making the butterfly go through a large amount of pressure to fan Matilda.
Unfortunately, this causes the butterfly to fall apart. One of its wings (leaves) fall off, Matilda becomes alarmed and quickly places it back on again. However, the same does with the other wings and the head. This causes Matilda to faint. The pigs, satisfied with the reaction, comes over to steal the eggs. The real butterfly attempts to revive Matilda by fanning her with the wings again. This makes Corporal Pig bring out a fly swat, and attempts to kill the butterfly. However, it is too fast and lands on a pigs head. Corporal Pig swats the pig, as the butterfly flies out of the way. This causes the pig to scream, catching Matilda's attention. She shadows them, Corporal Pig brings the eggs to her, This causes Matilda to become angry, put the eggs down, Matilda scares them off and the pigs run away in fear, but she attack the pigs.
The real butterfly comes over to land on Matilda. In a cool breeze. However, when it stops, Matilda yells. It is revealed that the pigs, severely injured, are hanging onto a tree branch in a stack, with Corporal Pig on top, fanning Matilda with large leaves, similar to a butterfly. Matilda's yell causes them to speed up fanning.
This was the first episode to feature a Fake butterfly.
The episode name may be a reference to a 2004 American Science fiction psychological thriller film, The Butterfly Effect. It could also be named after the Butterfly Effect in the Chaos Theory, as shown by the wind produced by the butterfly.
This episode dates in 2013 with the credits instead of 2014.
