In the Game Boy Advance version, a number of Easter eggs referencing previous Rare titles can be found in Cranky's Hut:
• The mask of Mumbo Jumbo from the Banjo-Kazooie series can be seen sitting on a barrel in the foreground.
• The mounted head of Sabre Wulf, the main antagonist of the Sabreman series, can be found hanging near the door. He does not appear to be dead, as his eyes continue blinking despite being decapitated.
• Next to Sabre Wulf's mounted head is a picture frame showcasing a compressed image of artwork for the 2004 Game Boy Advance game Sabre Wulf.
