The Ninja impling is an impling that can be caught in the Impetuous Impulses minigame, and are located throughout Puro-Puro and Gielinor. The player needs at least 74 Hunter to capture this type of Impling or 84 to catch it barehanded. To catch the Ninja Impling, the player needs either a normal or magic butterfly net and some impling jars. Once these requirements have been met the player simply needs to click on the Ninja Impling, and the character will attempt to catch it, though there is a chance of failure.
When the Impling is finally caught the player can either trade with Elnock Inquisitor or can free the Ninja Impling, which will leave an item behind. The player can get 3 impling jars for one Ninja impling. Capturing a Ninja impling will grant the player either 50 (if caught in Puro-Puro) or 240 (if caught in RuneScape) Hunter experience.
At current Grand Exchange prices, opening a ninja impling jar gives 16,048 worth of loot, on average. This means opening ninja impling jars marks an average profit of -15,183 per jar, however this does not include loot from clue scrolls.
On average, one would profit -379,584 to get a hard clue scroll from ninja impling jars at current Grand Exchange prices, excluding the rewards from the completed Treasure Trails.
