 According to Bumpass , Squidward was " a very nasally , monotone kind of guy " . He said the character became interesting to perform because of " his sarcasm , and then his frustration , and then his apoplexy , and so he became a wide spectrum of emotions " . Tom Kenny , the voice of SpongeBob , describes Bumpass recording his lines in the studio , saying , " I love watching Rodger ... He 's right next to me " . According to Kenny , when Bumpass " goes apoplectic " as Squidward while recording , his head turns red , " and you 're afraid he 's going to have an embolism " .
