With images via TF08, we have a lit­tle descrip­tion about the Skids char­ac­ter (Green Chevy Beat/Spark):

Because he is slightly less hyper­ac­tive than his brother MUDFLAP, AUTOBOT SKIDS has always thought of him­self as “the smart one.” He likes to point this out at every oppor­tu­nity. While MUDFLAP zips around like a maniac, AUTOBOT SKIDS prefers to impress his supe­ri­ors among the AUTOBOT high com­mand by behav­ing in a way he thinks of as mature, which usu­ally involves talk­ing non­stop about any­thing that occurs to him.
