The credits at the end of the movie are pink colored to match the monster's color.
"Blob Wrangler" is one of the texts in the credits.
[unused disclaimer, written for end titles; ended up on cutting-room floor] THE BLOB contains a purely fictional account of a small group of ruthless and corrupt military agents. These characters do not represent the United States government, and it would be erroneous and unfair to suggest that they do. The vast majority of North American Armed Forces personnel have demonstrated the utmost moral sense, regard for civilian welfare, and worthiness of the public trust.
