Atcommands monsterbig and monstersmall seem to be a slightly modified, out of date copy of @monster. I suggest the commands be merged into @monster. The method is similar to how @clone/@evilclone calls a single atcommand clone function which checks the command string to determine the appropriate behavior.
An example patch for trunk can be found
here.
