Netflix has faced criticism in the past for including inappropriate content in their kids' shows, such as overly sexualized images or references. While it's possible that some instances of depicting characters' butts in a comedic context could be seen as harmless or humorous, it's clear that not everyone finds this type of content appropriate for children.
It's important for streaming platforms to carefully consider the content they include in kids' shows, as well as how they present it. If enough viewers express their concerns about these types of depictions, it may prompt Netflix to reconsider their approach and make changes to ensure that their programming is appropriate for all audiences.
