I really like the alarm clock idea! If you get it wrong, the RF alarm could sound really loud (the one from the AO opening FMV when Abe says 'Get me outta here!')
Whilst we're on the subject of alarms that make you solve something, how about a slig lock talking alarm, with buttons corresponding to gamespeak phrases? To turn off the alarm you must repeat the code, which could be randomly generated or from a selection of say five different ones.
Same principle could also make an Abe and native mudokon alarm with whistle and fart codes! Only issue would be whether you could hear the gamespeak properly over the alarm
