The Tigers have announced that they are bidding to bring around 3,000 fans to Odsal tomorrow.
Castleford say they were lifted by the 2,500 supporters who travelled across the Pennines to follow them against the Salford City Reds last month and are relishing the challenge that the Super League leaders present.
Now Bulls chairman Chris Caisley is hoping they keep their word to ensure another crowd in the 17,000 region.
"Warrington made a lot of noise about bringing thousands of fans with them and had they done so we could even have topped the 20,000 barrier," he said.
"But let's hope Cas keep their word - it will certainly add to what is sure to be a great atmosphere."
Far from being intimidated, Stuart Raper's side seem to thrive on it and club spokesman Mike McDonald says the Tigers will be up for it.
"There's no fear here," he said. "There's a lot of respect, the Bulls are a very good side but Stuart's preparing the boys to bring the two points back to the Jungle."
The Tigers have made a mixed start to the season losing surprisingly to Halifax in the fifth round of the Challenge Cup and their opening Super League clash at home to Wigan.
But they lifted morale with victory at Salford and last week picked up the points again in a tense struggle with London Broncos at The Jungle.
They still haven't really hit the heights of last year though when they knocked out Wigan and Leeds in the play-offs only to fall in the semi-final to St Helens.
And this week they have moved to strengthen their squad following injuries to Richard Gay and Jason Flowers.
Raper has snapped up former St Helens winger-full-back Danny Arnold on a month's loan from Huddersfield-Sheffield Giants.
The 22-year-old Arnold, who played in Saints' Wembley cup final wins of 1996 and 1997 over the Bulls, is set to make his Tigers debut.
There is also some good news on the injury front with Danny Orr, Michael Eagar and Aaron Raper all likely to be available.
Raper has recently been on the sidelines with a shoulder injury but the word from the club is that he has responded well to treatment.
Orr (ankle) and Eagar (groin) picked up injuries against the Broncos last week but Raper will be desperate to get his best men on the field.
