A raccoon was trapped when it tried to climb out of the sewer through a grate in the pavement. The Wildlife Rehabilitation Center came to rescue the raccoon that was later named Walter.

"Every year we get at least two or three raccoons with their heads stuck like this; it's this particular style of grate that does it," said Scott Diehl, director of the Wildlife Rehabilitation Center, according to The Dodo. He also added that the pointed shape of a raccoon's head makes it easy for the curious creatures to get stuck in things: "It's like an arrow that is not very easy to pull out once it goes past a certain point."

A kind passerby saw Walter's head poking out from the sewer and placed an A-frame road sign next to him in order to keep him safe. A ledge by Walter's feet kept him from hanging.

The rescue wasn't easy since the raccoon was petrified of people and he kept on struggling to free himself.

"He was very tired but still had enough gumption in him to struggle," Diehl said. "He was so tense, struggling and very, very frightened, that we weren't able to get his head worked out of the hole without his struggling."

Walter was given sedatives so he could calm down and his head was removed from the grate. Walter didn't sustain any physical injuries from the incident and he was brought to the wildlife center where he was monitored for a few hours. The raccoon was in a good health condition and even showed his naughty side while in the shelter.

"He did what raccoons normally do in housing overnight," Diehl said. "He ate every scrap of his food and flipped his water bottle over and shredded up his newspaper for bedding and tipped things over and made a royal mess of things. But that's typical for raccoons."

Since Walter was in a good condition, he was released back to the wild.
