Hi! Rena here!
We're gonna play with fireworks at Komatsu-san's workshop.
There are many different kinds of fireworks and Rena likes them all!
Ushikou-san is gonna buy them for us. I wonder what kind he'll get?
I'm sure they'll be wonderful......probably!
Maybe you should try swinging 
your arms a little wider.
.ربّما عليك أن تحاولي التّلويح بذراعيك أكثر من ذلك
Probier mal, deine Arme
noch mehr mitzuschwingen!
Mueve los brazos un poco más intensamente.
Mueve los brazos un poco más rápido.
Tu devrais balancer les bras
un peu plus, comme ça !
Dovresti provare a muovere 
un po' più le braccia.
Talvez devesse tentar mexer mais os braços.
