The two remaining kids were Jon, a silent little boy, his affinity was Ice, and then Hansel, a former fat kid, who had now gotten pretty slim, he still has a timid personality, and his affinity is Earth. Both have conventional looks as Ice Giants' concern, such as yellow-gold eyes and silvery-white hair.
Jon was doing his hardest, but his icicle spears were not big or strong enough, he was slowly chipping away the dummy of ice but had to take rests for his mana to regenerate here and then, so he was taking his time. He's only five years old so it is rather normal.
And then there was Hansel, he had yet to find a way to launch his rocks, so he was grabbing them when he conjured them with magic and launching them with his arms, the dummy was also slowly being chipped away.
"Come one, you can do it!" I said.
"Hahh… I-Its hard…" sighed Jon.
