Frog enjoys wearing his spacesuit because he feels naked and defenseless without it.
His backpack is made of material that is somewhat intelligent, it only responds to his suit. If he's not wearing it then it will not strap onto him, let him open it, nor let him use the rocket.

He's very social and doesn't quite understand personal space, so don't when he's all up in your face talking to you.
He's able to grow extra arms whenever he pleases.

He was rocketed off of his planet during testing of a new spacecraft that turned out to be defected, which caused a ripple effect in space because of how powerful an explosion it caused back at the testing quarters and created a black hole that erradicated his entire planet and species as a whole.
