Well... this was kinda weird xD The scene where the button was pressed with the stretched out tongue was pretty strange, also, that background music ... just perfect, 10/10 xD
Could use either more color or motion with more detailed line art. But the humor which came from the mistake is still there ... or something
Neat. Keep this up ;) Also, your singing skills are awesome, keep using them more often and in more creative ways! ;D
A well done animation! Good job!
