Trade Me has released its list of the top 10 presents for children, and four of them need to be bathed, grown or dissected to be revealed.
"There's Scruff-a-Luvs, the neglected and abandoned animals that need rescuing. These little critters arrive as a sad, matted ball of fur but with bathing, brushing and loving, kids reveal the pet they really are," says Trade Me spokesperson Millie Silvester.
"We can also expect kids to be dissecting slimy aliens and saving the galaxy with the hot new treasure X Alien toys.
"Kids have to surgically extract one of 18 treasure hunters waiting to be rescued from inside a slimy creature's belly."
Other toys to make the list include the Blume collectable dolls, which grow out of a flower pot, and a twerking llama from ZURU Pets Alive.
And muggles finally have the opportunity to become invisible with the Harry Potter Invisibility Cloak.
"Parents may be wondering where their children have gone this Christmas," Silvester says.
"The high tech coat works like a greenscreen and uses an app to show the wearer disappearing in photos and videos."
Silvester advises parents to get in quick to get the hot toys you want.
"The top toys often sell out well before the big day so if you want to ensure your little one has exactly what they asked for, it's worth preparing early."
