In my head, baby Goob has the personality of a less expressive Stitch and since goobs have stretchy arms, can hang off his Mom/Dad like the sloth in the croods. He will climb on people he likes.

One day, when he is big, he might have to go hang out with the sylphs. For now, though, he is content to hang on in hooded cloaks, various bags and run amok with urchin children in various locales
