Limericks

I’ve entered a limerick competition. Can you help me get to the next round?

Teh maskde adn Nwe Zealadn haev ailde.
Btu nto teh commno ro scalde.
Teh buttosn aer faek.
Fride egsg kwke-kwke maek.
Whta creatuer haev ew surveillde?

Fi yuo add em ot crackre ro fyl,
Yuo will gte pretyt lighst ni teh syk.
Fi yuo maek em a wall
I will filtre ti all.
Cna yuo figuer em otu? Whta ma I?
