The only time i imagine Big Man as a manta ray is when theyre in bed and hes becoming Big Blanket theyre usually very sweet tho, i like to think shiver is a sap and very lovey dovey and theatrical and frye is much more chill like "Ohh my beloved dear partner frye, would you please join me in this delicious brea-" "yeah babes sure" big man is kinda in between shes nervous and sweet but more chill than shivar
