Sam, Tucker and Danny get tired of drawing out Danny's summoning circle (which they use for quick transport and emergency evacuation of Danny from difficult situations. Or just to force him to take a break from heroing) They get a stamp with Danny's summoning circle on it for extra convenient summonings (perhaps circles that do not intend to bind the summonee into place can be Small and Stamp sized.... or they summon Danny as little baby man) just dip the stamp into Whatever (ink, blood, waterver else can be used) and Stamp it where you need it
genuinely a big brain move. They have to be sure to make sure that stamp doesn't get lost though. The chaos that would cause would be too terrifying to fathom
