Kids of all ages will soon bid farewell to what was once a hallmark of childhood.

Toys "R" Us is going out of business, closing all of its 740 stores in the U.S. over the coming months. The 70-year-old retailer had been a stalwart in the bricks-and-mortar battle against Inc. (AMZN) , but it seems even Geoffrey the Giraffe couldn't withstand the Amazon effect.

CEO David Brandon told employees Wednesday that Toys "R" Us will liquidate all of its stores in the U.S., but will try to bundle its roughly 200 stores in Canada to shop for a buyer. The company's online operations are expected to continue for now in the hopes of finding a buyer.

The chain filed for bankruptcy in September, citing $4 billion in liabilities at the time. The holiday shopping season looks to have simply not been strong enough to get Toys "R" Us back on its feet.

In the United Kingdom, the company will close all of its 100 stores in six weeks, costing about 3,000 jobs. According to the BBC, by Wednesday, March 14, about 25 stores had closed in recent days or were due to shutter doors by Thursday, March 15.

As Toys "R" Us begins the shuttering process, numerous disheartened fans took to Twitter to lament the loss. Here are some of the saddest scenes.

#ToysRUs dead! Brighton shop completely cleared out on 2nd day sale. Soon a memory kids won't know, like Blockbuster, Woolworths, Tandy, and WHSmith Video ! Nostalgic and depressing seeing signs they hadn't changed since I was a kid, especially the exit. RIP @gamesyouloved

Sad times for @ToysRUs who will close all UK stores in six weeks with 3,000 jobs lost. The company failed to find a buyer after going into administration. People here in North London have come to snap up the last bargains. #ToysRUs ��

Sad to see #ToysRUs closing down, I grew up on the Toys R Us tv ads and shopping in store.

Back in 2015, TheStreet's Brian Sozzi caught up with Toys "R" Us CEO David Brandon, who explained at the time how the company planned to compete with Amazon and Walmart Inc. (WMT) . It seems even best laid plans didn't work in Toys "R" Us's favor.
