Series 4 of The Trash Pack came out in December 2012 in Australia, and didn't arrive to the USA until July 2013.
Special Finishes
Series 4 introduced three new finishes, while ditching the ones introduced in Series 3 (Wall Crawlers and Color Changers), these new finishes being Biters and Minis.
Reveal and Leakage
In the early Fall of 2012, a YouTube user uploaded a video with Series 4 information, claiming that he found it on the street near Moose's headquarters. In the video, he showed the packaging of a 5 pack, which included an image of Squish Bone. (Other Trashies that could be identified were Mouldy Melon and Mucky Ducky) along with a wheelie bin. When the page was shared on this wiki by a wiki contributor, the buzz began, and soon, dozens and dozens of Trash Pack fans were aware of the new series. Because the video was blurry, many people could not make anything out of the things seen in the video, making many assume that the video was a hoax. When asked for photos of the item, he agreed to take them. ....for a limited edition! In late October, Moose found the video and issued a copyright claim, forcing Youtube to take the video down. Shorty after, the Trash Pack website displayed a teaser image with a silhouette of a square bin flying over the moon (a reference to E.T?) with the words "Series 4, Coming Soon" displayed. Quickly after this, Series 4 info was leaked yet again in the Trash Pack Facebook page. An image of familiar Hard Rubbish characters from Series 1, 2 and 3 was posted. However, one Trashie was not familiar. The video game controller Trashie, was thought to be an upcoming or unreleased character. He was later released in Series 4 as Banged Up Gamer.

Trivia
- This is the first series to include Food of the World and Trash Toys.
- This is the first series to deviate from the classic Trash Can packaging for figures, which became a tradition until the series' end.
- Even though mini trashies are a special type of Trashie, they are not listed as special editions, but as rares.
- This was the first series to exclude Ultra Rare as a rarity from all figures outside of the Ultra Rare team, Beach Trash.
- Each 5 Pack always includes one of the following three types of Trashies: Mini Trashie, a Beach Trash, or on occasion, a Limited Edition.
- It took this series seven months to get ANY release outside of Australia. This is the longest any Series has taken to be released, unless Wave 2 of Series 3 is counted. (Ten months)
- This is the first series to exclude Bin Monsters and Bin Critters, two teams that were a big part of the original trio of series.

Series 4 is out now
