What Photos Do I Need To Take For Zeke On Poptropica Why Can't I Take Photos Fast With My Canon Rebel XTi?

Why can't I take photos fast with my Canon Rebel XTi? - what photos do i need to take for zeke on poptropica

I try to take a photo of pets, so they have to take pictures quickly and easily. When I press the button, it takes the picture and says BUSY. Then he told me to take the next picture. Can someone tell me, to adapt to my images quickly and clearly, without a busy signal? Also know what kind of lens do you suggest for a photo of your pet?
