This is the version of hop attack I use for my bullywugs.
HOP ATTACK: The bullywug can leap its full movement without a running start. If the bullywug jumps at least 10 feet, it may land in a space adjacent to a target and take the attack action with its spear, doing an additional die of damage (like a crit). A target struck by the hop attack of medium size or smaller must make a STR save (DC 11) or be knocked prone.
