Throughout the band's formative years and first three albums, they failed to maintain a consistent lineup, cycling through ten different instrumentalists up to the release of The Stomach for It.
[7] The band has toured with various artists such as Funeral for a Friend, Escape the Fate, The Amity Affliction, and label mates Victorian Halls to promote the release of If You Don't Have Anything Nice to Say.
Shortly after the publication of The Stomach for It, Hutka left the band for unknown reasons and was temporarily replaced by Chris Paterson, the former vocalist of Jamie's Elsewhere.
In February 2013 The Bunny the Bear announced their fourth studio album entitled Stories for April 16, 2013, from Victory Records.
J.C. Maçek III of PopMatters said in a positive review of the album, "The overall impact of The Bunny the Bear’s Stories is that of a well-unified whole that might alienate as many listeners as it entices, for many of the same reasons.
On May 19, 2013, Matt Tybor announced on The Bunny the Bear Facebook page that Hutka had departed from the band due to ongoing battles with drug addiction.
It has been stated by many of the groups touring musicians that Hutka's struggle with addiction was the primary source of turbulence throughout his time in the band.
On February 11, Tybor announced on Facebook that a remastered edition of the band's debut album The Bunny the Bear would be released on April 11, 2016.
Tybor also released two "rarities" albums throughout late 2016, featuring more unreleased TBTB demos as well as songs from his various side projects.
Coinciding with this, their seventh studio album entitled The Way We Rust was formally announced, scheduled for release on March 17, which will feature vocals performed by Joseph Garcia.
On July 10, 2021, Tybor announced via the band's official Facebook and Instagram pages that former member Chris Hutka had died.
In 2012, Tybor formed a short-lived side project called "A Liar Wrote This Symphony," featuring himself on vocals, Doug White on guitar, and Val Hill on drums.
Five of the project's demos were re-recorded as The Bunny the Bear Tracks: Somewhat Standards, Lover's Touch, Curtain Call, Motions and Sleep Sequence (from A Liar Wrote This).
Also in 2012, Tybor created a solo project called "Ovaries," which featured a darker electronicore sound that would later be heard on The Bunny the Bear's fifth album, Food Chain.
Ovaries released four demos titled "Food Chain," "Logic," "Secrets," "The Butcher, My Bride," and "The Melody The Memory."
In 2014, Tybor and White formed a new project called "When Wild Dingos Attack," featuring an aggressive metalcore and grindcore-influenced sound.
In July 2016, Tybor formed another project titled "Ramblings From the Rabbit Hole", which included himself as well as his long-time friend and poet Duke Donaldson.
In September 2016, Tybor announced plans to release a rarities album featuring songs from A Liar Wrote This Symphony and Ovaries, as well as some The Bunny the Bear demos.
In June 2018, Tybor created an alt pop musical project called Prblms with producer and singer/ songwriter Anthony Todorov (also known as Artemis).
The duo released Prblms debut single titled 'prison' which reached over 1 million streams on Spotify within 3 months.
Tybor and Anthony went on to release four more singles as prblms titled Tr4$h Talk, Ghosts, Sucks Without U and Pushing Daisies.
