The duo both arrived at Goodison Park this summer and combined as Naismith struck a first half hat trick during a 4-1 win over AEK Athens last night in Hibbert's testimonial.
Veteran defender Hibbert, who also scored in the game, sparking a pitch invasion, admits he has been surprised by the former Rangers man since last month's move to England and how easily he has settled into life on Merseyside.

"It shows what he is capable of and in the proper games when he is fully fit, there's a lot more [to come] of him.
"He's a new player, he's settled in quick. It does take time for a new person to come in and settle down but it doesn't show there. It was like he's been here for four seasons.
"I think the manager's brought him in for that. I think he comes in off the line, if he plays him out wide right or out wide left, he's got the will to come in and run round and make runs like you saw [against AEK Athens] and that's very hard to defend really."
Pienaar secured his long-awaited return to the Toffees last week in a £4.5 million deal and his year-long absence from Goodison had not lessened his impact as proven by last night's performance, which followed on from an impressive spell on loan from Tottenham last season.
And Hibbert claims the South African continues to fill defenders with dread and, with Naismith, can terrify opponents when the Premier League season kicks off in 10 days' time.
He added: "Steven is world class. He'll play balls in, he will make runs for you and makes it a lot easier down the left [hand side] for you because you know what you're going to get from him. I don't think any defender likes playing against him.
"What we've got now with the ability of Steven [Naismith] and Steven Pienaar is frightening."
