The outfit sold on Monday was specifically used for work outside TV studios and stunt work, while the other original costumes were reserved strictly for inside studios.
It also featured prominently on Mr Blobby VHS home video releases.
Stowe added: “We were blown away by the interest in this sale.
“People love nostalgia. Imagine walking in to someone’s home and seeing Mr Blobby in the corner. It’s the ultimate talking point.
“Discovering and selling these amazing pieces of pop culture history is a complete pleasure.
“In my job, one day it’s fine art and sparkling jewellery; the next, it’s Mr Blobby.”
After appearing on Noel’s House Party, the chaotic, bright pink and yellow-spotted character became a national and cultural phenomenon called Blobby-mania.
It was the centrepiece of the Blobbyland theme park at Cricket St Thomas in Somerset – and even beat Take That to the UK Christmas Number One spot in 1993 with his own self-titled single, Mr Blobby.
The costume was originally owned by the late Mickey Wills, Blobbyland’s former head of entertainment, who also performed high-energy shows daily at the theme park.
