Rumble is a "small" 'bot. Compared to the other Cybertronians, that is.

And, well, I guess Soundwave thought that if Rumble ate enough Energon cubes, he would grow bigger, because you saw this:

Soundwave had put his son(is Rumble his son..?) In one of those high chairs with the tables you see toddlers in, put a red bib on him that said "Badassatron" in capital yellow letters on it, and made him eat a bunch of Energon cubes.

Rumble has a slightly heartbroken expression, his servos and face stained and dirtied from the Energon cubes his plate was still accumulated with. He looks like he'd cry if he could, with a big frown on his face and his visor looking a bit dimmer and glossier than usual.

Soundwave: Rumble: must eat all Energon cubes if result: big bot.

Soundwave probably didn't know this would hurt his son's feelings, and you knew he would apologize if he knew, but it was still kind of sad to see the look on Rumble's face.
