Federal authorities said the dupes may not comply with federal safety standards.
Action News recently spoke with the CEO of Sunny Days Entertainment, who makes the real Squeezy that is often impersonated by other retailers.
At the time, he told us the counterfeits are also on his radar.
"The counterfeits have a really small thickness because we make ours where they withstand about a 30-pound stretch, which is pretty strong," said Melvin Wells with Sunny Days.
And while the CPSC stopped over 350,000 counterfeit squishes from entering US ports, copycat items are still showing up online, on social media, and in discount stores.
And Consumer Reports says some may contain potentially hazardous or unsafe materials.
"Our safety experts bought several toys and tested the gel inside, and one had an acidic pH, the same as lemon juice or vinegar. And a pH like that can cause severe skin irritation, especially in children who have more delicate skin," said Gabe Knight with Consumer Reports.
Consumer Reports found concerning reports filed with the federal SaferProducts.gov website, claiming children suffered chemical burns after their squishy toys burst open.
So here are a few strategies to keep kids safe.
First, don't give gel-filled toys to babies or toddlers.
Check for holes or tears frequently. If one does break on your child's skin, wash it off right away and throw out the toy.
If you have concerns about a toy's safety, report it to the CPSC on SaferProducts.gov.
The warning from the CPSC also comes as dangerous social media videos encourage kids to microwave squishy toys, which safety experts say is never safe.
Heating these toys can cause them to burst, releasing hot, sticky material that can cling to skin and cause serious burns.
