Tyrannosaurus Alan is a stupid retarded dinosaur that always wants BREAKFAST! from George Volcano. He is also drunk from drinking abysmally mind-controlling conker juice with BREAKFAST! Mixed with blood (in Volvic Revive), which if you spill on others (except un-defeatables like Chuck Norris), they will melt into red slime.
The BREAKFAST! Alan wants is actually you. If you're a sabertooth tiger, you better doubly watch out.
Despite his maniacal behavior, Alan defends pterodactyls from George's speciesist remarks.
