You got most of it quite right, except the ending.
It’s -erle, or really just -le (depending on where you split the word).
The suffix is used to change a word to sound smaller, cute, playful and generally less serious.
It also has a southern accent/sound to me, but take that with a pinch of salt.
Not sure if there is an english comparison.
Its similar to another german suffix: -chen
