Henry's $18,000 airfare from England is about 10 times his value, but trainer Allan Jarvis is unconcerned.
Jarvis knows he can't win next Tuesday's A$4 million Melbourne Cup with Jardines Lookout without Henry's help.
Henry stands a little over one metre tall, but he is the kingpin of the JardinesLookout juggernaut as one of the world's finest staying talents.
He is the miniature pony who Jardines Lookout refuses to go anywhere without.
Even from England and into the mounting yard on Melbourne Cup day.
"Look at the two of them," laughed Jarvis when Henry got excited as Jardines Lookout came back to the tie-up stalls after a gallop at Flemington yesterday morning.
"They're like an old married couple - they squabble all day, but can't do without each other."
The unlikely pair fell in love three years ago.
"Jardines Magic used to be a very nervous type and wouldn't eat.
"We put him out in the paddock, he teamed up with Henry and they've been inseparable ever since."
Henry will create a stir on Melbourne Cup day.
"I've even got permission for him to accompany Jardines Lookout in the pre-parade after he's been saddled."
That won't do much for Henry's self-image.
Jardines Lookout weighs only 415kg, light for a top-class stayer, but he impressed his Melbourne Cup rider Patrick Payne in yesterday's gallop.
"He feels stronger than he looks," said Payne after a gallop that was considerably quieter than Vinnie Roe's hit-out.
"He's a very clear-winded horse and he's ready for the race now," said Jarvis, who is hoping for a fast track.
At 56kg, Jarvis believes Jardines Lookout can beat Vinnie Roe, something Mark Weld, son of Vinnie Roe's trainer Dermot Weld, does not agree with.
"With all respect to Mr Jarvis, the record book tells a different story."
Jarvis believes the fast tempo of the Melbourne Cup will suit his horse.
"We met Vinnie Roe in the [Ascot] Gold Cup and a 2 1/2-mile race turned into a 1200m sprint. It was ridiculous and it didn't suit us."
