Simply click on the image and it will open full size - it's nice and big so you could even print it on to an A4 piece of paper if you wanted to and it would still look nice and sharp. Print however many you need for the number of guests you are inviting.
If you would like to make a 3D paper craft of Pascal the chameleon click on the image below and it will take you to the Disney page where you can open and print the PDF document.
Before you go, make sure you watch this cute video of pascal, Rapunzel's pet chameleon in Tangled. Oh and if you'd like some Tangled coloring pages for your party (maybe you can hand them out with your favors) you can find Tangled coloring pictures by clicking here.
