Floyd uses unspecified attack magic during Vargas Camp while fighting the mine monster, uses magic to help Riddle and Stitch build a cottage and refers to color-change magic as “basic baby magic,” offering to teach Ace and Deuce how to use it properly, so that is possibly a spell at which he is adept.
He also has a voice line about drawing on a wall of the school using magic.
Like Azul, Floyd might be capable of precise magic use, with Ruggie complimenting him on his ability to hit wood with fire magic during Vargas Camps in the midst of the chaos of the Vargas Monster’s attack.
Jade says that his magic manifested in the later years of elementary school, two months after Floyd.
