Get an old plastic dino. make sure the dino is big enough to hold a plant and is deep enough to hold the roots. If you dont have them lying around, you can probably pick them up at a vintage store.

cut a slit behind the neck and above the tail about the same size. and use heavy duty scissors to the cut the rest of the rectangle.

spray it with glossy spray paint and let dry. repeat till the original colors gone.

the paint i used

using a color close too the original color, paint the feet of the dino. let dry and paint it again. then use your sponge and lightly apply pressure to the belly of the toy. slowly add more pressure as you make your way down the legs to the feet. if you mess u can use the back of your sponge (the clean side) to swipe up wet paint. btw make sure to dab the paint on, not swipe.

after letting every thing dry make sure to paint a gloss over your reptile so the water doesn't wash all your hard work off.then using a needle poke enough holes for water to escape out the belly of the dino.

and your done. throw in some potting soil and put in a plant. btw sorry for my crappy plant. I was to impatient to grow anything so I just plucked something from the yard to make the picture.
