The trident is the only straight line on a page made entirely of curves, which is exactly why it is worth having: it gives a child one edge to keep honest while everything else forgives a wobble. The three prongs are evenly spaced and the shaft runs the full height. This mermaid coloring page with a trident suits six and up. The starfish is the gentler version.
