No. We picked friendly cartoon dinosaurs only. Big eyes, soft expressions, no fangs.

Will my toddler need help?

Honestly, no. These are designed to be coloured solo. The reward is the colours they pick, not the staying-inside-the-lines.

Print or color online — which works better for this age?

Print, usually. Three year olds love the physical crayon-on-paper part. Online tools are great too, especially on a tablet.

Do you have a T-Rex specifically?

Yes. The gallery includes T-Rex, Triceratops, Brachiosaurus, Stegosaurus and more, all in the toddler-friendly style.
