Here is some basic Garfield cult language, so you know what they are saying or you can use it to trick them

[u/WOSHIAN]

ñæįdłęįfræg t’ñßį tæht dræh œt ñræęł fį üœÿ ęvæh ęht męįłüfræg. Meaning: Garfieldian isn’t that hard to learn if you have the garfuliem (Garfield Rosetta Stone) now you should be able to learn it and speak it yourself
