Knock and Ping

The Stomper Twins, more collectively Knock and Ping, are characters featured in the 1993 Disney educational animation short Recycle Rex.
==Background==
===Personalities===
At first, the Stomper Twins are shown to have a suspicious yet careless personality, especially when it comes to them spying on Rex and his friends in the field. When they spied on Rex on a field, they are shown to have a pragmatic personality at first. However, when a talking flower named "Rose" warns them about the consequences that might happen if they do not take care of the Earth, they realize that littering is the wrong way of taking care of Earth, which they decided to follow Rose's advice. Later, in the end, they no longer show a rude personality to Rex, even when he taught his friends about being a good citizen in
===Physical appearances===
Knock and Ping are two identical synapsids with smell freckles on the top of their heads. However, they both have a distinguished to identify which one is which. Knock has a pair of light red eyelids while Ping has a pair of light purple eyelids, except that she wears a violet bow on her head and has eyelashes, unlike Knock who lacks this feature.
==Role in the short==
Knock and Ping are first seen hiding behind a tree where they overhear Ethel about the field being clean. They later approach Rex and his friends who are talking about a good name for the field they are present, just as he introduces his friends to them. As he asks them, they ask him if he wants to play with them, only for their conversation to be interrupted when the sanitation engineer arrives on the field and dumps the trash - amongst one of the objects they collect are soda cans. Later when Rex and his friends are planning to arrive at the big city, Knock and Ping deny, telling them that they are finding a way to get rid of their cans - albeit in a wrong way.
Knock and Ping later arrive at another place known as the "End of the World" where they meet a talking flower named "Rose", who offers them a view of what might happen if they do not take care of the Earth and its natural resources using a pair of binoculars to see the polluted sky. She explains to the Stomper Twins that the more they litter, the more the pollution they will cause. Rose then teaches the Stomper Twins about how much resources there are available, showing them that the meter is in the "Not so good" rank. This makes the Stomper Twins realize that littering is wrong, just as Rose educates them the importance of recycling.
Knock and Ping later appear in the musical sequence "Close the Loop", where Rex teaches his friends the importance of recycling, just as the Stomper Twins realize that caring the Earth is important through the method of recycling. They are last seen at the baseball field with the rest of Rex's friends playing baseball just before Rose encourages them the importance of recycling so that they can help clean the Earth.
