The school unveiled the new design, which was created in cooperation with the Walt Disney Co., last week, and since then two Facebook groups, a YouTube video and an online petition have been created to demand the return of Sparky's old look, The Arizona Republic reported Monday.
The school's Undergraduate Student Government passed a resolution last week seeking to have the new mascot banned from sporting events. A student referendum, a purely symbolic move, is being planned for next month.
ASU President Michael Crow said officials are meeting with student leaders to discuss the issue.
"We're getting pretty mixed reactions to the new Sparky," Crow said. "Some unhappy alums, some unhappy students. Some happy students, some happy alums. Lots of people who say, 'Who cares?' Other people who say, 'It's really important.' They care a lot."
The new version, which features larger eyes and bulging muscles among the changes, is scheduled to officially take over from the old design April 13.
