The game is likely "The Adventures of Timmy" (also known as "Timmy's Adventures"), released circa 1994-1996.
It was an educational/edutainment title often bundled with sound cards or early multimedia PCs. If this isn't it, The Incredible Machine (contraptions) or Lego Island (building) are other 90s creative PC games, but "Timmy" fits the "blue guys/team" description best.
