Don’t monkey around with your holiday shopping.

If you’re toying with the idea of getting a head start on holiday shopping, consider stocking up on the season’s hottest toy while it’s still on shelves. Fingerlings—finger-sized plastic monkeys that sit on your digits and blink and respond to touch, motion and sound — were among the best-selling toys during the month of September, according to The NPD Group, a market research firm.

Created by the Hong Kong-based WowWee, a robotic toy manufacturer, Fingerlings launched in August and retail for as little as $14.99 at stores like Walmart, BestBuy and Toys R Us, but due to their seasonably high demand, they’re being sold on third party sites like Trendly for up to $180.

The Fingerlings, which each have a name (Zoe, Mia, Finn, Boris, Bella, Sophie and Gigi to name a few) have their own collection of accessories like monkey bars, swing sets and see-saws for $39.99—if you can track them down.

Here’s a look at the hottest toys since 2010:

2016
Hatchimals
These interactive toys that hatch from plastic eggs and learn how to walk, talk and play games were all the rage during the 2016 holiday season when they retailed for $59.99? Retailers quickly sold out of their inventory and websites like eBay had them listed for up to $1,000.

2015
Pie Face Showdown
Nerdwallet reported that the Pie Face Showdown topped the charts for the most desired toy of 2015. The $24.99 game distributed by Hasbro smacks whipped cream in the face of players on the count of 3 as they fight to be the first person to press a button.

2014
Jakks Pacific Sing-A-Long Elsa Doll
The Disney movie Frozen came out in late 2013 earning $1.2 billion at the box office — which may help explain why the $39 singing Elsa doll from Frozen was one of 2014’s year’s most popular toys.

2013
Furby Boom
According to Walmart, one of the top toys of the year was the Furby Boom, a multicolored, interactive pet that learns to speak the more it’s played with. The starting price for one of these fuzzy creatures is $89, but Walmart also a version for over $200.

2012

After 14 years in retirement, this $54 owl-like Furby creature took the top spot on the toy charts in 2012.

2011

The remote controlled $29.99 Air Hogs Hyperactives line of stunt vehicles proved to be the hottest toy of the year.

2010
