The first season from 2015 had Advantage Audio doing the sound effects for the show, but the problem is that they heavily used Hanna-Barbera sound effects which are very out of place in my opinion.
They should switch to a different sound effects company for the next seasons of the show, mainly those that use the classic Looney Tunes sound effects, either DigiPost TV or Glenwood Editorial. Sign this petition so they can change the sound effects for the show's next seasons.
