Thieves nabbed 18 baby salties in April, snatching the tiny reptiles from their pens at Crocodylus Park at Berrimah.
The search for the missing crocs, worth about $1,000 each, was abandoned some months later but now it appears at least three escapees have ducked their captors.
"It was an angry little thing, it was really, really upset," Bees Creek resident Christine Osborne said of the tiny croc that turned up on her driveway last Friday night.
She was told to duct tape the mouth of the 900mm croc shut and "wet it down and then put it in a pillow case".
But rangers couldn`t get to the house until the following morning.
"It was so funny, he said `I can`t get a car out at the moment, do you mind keeping it home overnight`," she said.
"I`m on my own at the moment (because) my husband`s interstate and I thought, `Oh, okay`. I thought I suppose he`ll be alright. He can`t bite me and he really can`t go anywhere."
She left the angry little reptile in the kitchen.
"(But) halfway through the night I heard this racket ...
"When I came out to the kitchen to find out he was gone I thought, `Oh gosh` ... I had to start hunting around the house at three o`clock for this croc ...
"There was furniture knocked over in the lounge room and he`d got out of the pillow case."
Ms Osborne wrestled with the saltie, who "fought like blazes, swinging his tail from side to side" and got him back in the pillow case.
"I popped him in the walk-in robe and shut the door," she said.
Ranger Tommy Nichols, who picked up another tiny croc on the same street the next day, said there could well me more baby crocs on the loose in the city`s outskirts.
"These two crocs both had markings on them and are believed to be the ones that were stolen sometime ago from Crocodylus Park," he said.
Corey Johnson, also of Bees Creek, said he was awoken on Sunday morning after his dogs started barking.
"(They) were barking and made a hell of a noise," he told the NT News.
"When I went to the backyard door I saw a croc sitting on our patio.
"We have no idea where it came from and what it was doing in our back yard - we don`t even have a pool or any water close by where it could have felt like being at home.
"I yelled a few `crikeys` and grabbed it and put it in a large container."
Mr Nichols said both crocs had scute marks on their tails, which is used to mark crocs in captivity, and they had been returned to Crocodylus Park.
