In this transformation sequence, our protagonist, Rex, returns home from shopping with supplies for the party his family wants to throw for his birthday, which was a week ago due to the holidays. In addition to the party supplies, Iggy has Rex purchase a costume of a character whose game was celebrating its 25th anniversary of its release shortly. Rex had played the game a bit before and was a fan of the character, plus the costume was a collab between the Wanderous, Inc. and a smaller, yet fast-growing costume supplier, so he felt obligated to help. Iggy warned him that it would still be a Wanderous costume, but the transformation would be more rapid fire than usual, and would hoped that he would find the change of pace intriguing. After putting on the costume, with the BK logo t-shirt being the final piece, the magic starts his journey into the himbo bear hero of Spiral Mountain, Banjo, at breakneck speed with some rhyming words guiding him.

Themes include muscle growth, weight gain, human-to-anthro-bear transformation, and golden-hearted himbo personality shift, and silly rhyming schemes.

Here is the 2nd stage of the sequence. The fast burst of energy quickly envelopes Rex’s body, as he observes the rapid maturation of his height and muscles faster than other transformations. His upper body being the most focused-on region as the fibers of muscle were literally-tearing the graphic t-shirt at its seams, their size enlarging to fit the character he was morphing into. His face, felt a tingle as its structure started to change, with his upper legs felt an itchy sensation appear under the yellow shorts.

This is the musclegut version of the sequence showing off Banjo’s body with clean, smooth pecs. Version and set differences are in the gallery description.

Art was done by the stupendous RegularTF on FurAffinity. First time I have worked with them, and they nailed everything. If you like male to male transformations, definitely check their page out. They are not taking commissions at the moment, but when they open, I would recommend trying to get one, as they have done some fabulous work. Here is a link to RegularTF’s page: RegularTF.
