Prince Of Caviar had a gentle jumpout at Werribee on Monday as Black Caviar's son ramped up his latest preparation.
Prince Of Caviar finished third in his 800m heat, beaten two lengths by a Danny O'Brien-trained All Too Hard colt but was not asked a serious question by Dwayne Dunn.
Co-trainer Wayne Hawkes said the trial was intended to be more educational than inspirational.
"He was good enough, they walked early and he just sat in behind them," Hawkes said.
"That would have taught him something and he was nice through the line.
"You just try and teach them - this is only pre-season stuff and we'll get serious when we need to.
"He's pretty Joe Cool as a horse, nothing much worries him."
Dunn said thetwo-year-old son of Sebring has made good physical improvement.
"He's done really well and is a different horse this time in," Dunn said.
"He's maturing well and learning all the time. He jumped well today and I could have led if I wanted to but the aim was to tuck in behind and teach him something.
"He's been on easy street so far and hasn't had any real pressure applied. He's put together well and is lovely and balanced underneath you.
"Obviously he's got the pedigree to live up to but he doesn't know that. He's only sitting in second gear at the moment and we don't know what his full throttle is."
