- Mentioned in The Season 13 Update, Keekre24 stated that he will not be using the 2013 CGI Diesel Model by Mattel because it is slightly rounded and it has a happy face, which does not suit Diesel's personality very well. Instead, he used the 2012 CGI Diesel Model by TOMY because it isn't as rounded as the 2013 model and it has a face that suits Diesel's personality best.
