This critter might be a tad too big.

The largest bullfrog tadpole on record was discovered by a volunteer at the American Museum of Natural History’s Southwestern Research Station in Arizona, researchers said Thursday.

Earyn McGee, PhD student at the University of Arizona originally tweeted an image of the freaky larva – to the horror, or delight, of many.

“A look through the scientific literature suggests this is the largest bullfrog tadpole ever recorded. Rare indeed!” said Geoff Bender, the director of the Southwestern Research Station.

While tadpoles are usually pretty small, the one in the picture has grown to epic proportions.

Researchers think its size is due to a hormonal imbalance and don’t believe it’ll ever metamorphose and turn into a frog, McGee said.

The record-breaking amphibian was found in a local landowner’s pond in March, as researchers drained the area on non-native predatory bullfrogs, Bender said.

Some Twitter users joked the overgrown tadpole was a baby Godzilla or said it looked like a creature out of Netflix sci-fi show “Stranger Things.”

“This is definitely going to haunt my dreams,” wrote @ocean_ginger.

The AMNH didn’t immediately return a request for comment.

McGee’s post had been liked over 3,000 times and retweeted over 1,000 times as of Thursday.
